Components Graphics Cards Reviews. Best Graphics Cards For The Money: April '09 : March Review/Apri. Detailed graphics card specifications and reviews are great—that is, if you have the time to do the research.
But at the end of the day, what a gamer needs is the best graphics card within a certain budget. So if you don’t have the time to research the benchmarks or if you don’t feel confident enough in your ability to pick the right card, fear not. We at Tom’s Hardware have come to your aid with a simple list of the best gaming cards offered for the money. March Review and April Updates: It's no secret that the brand new GeForce GTX 275 and Radeon HD 4890 have been released since our last update. Those two cards have been the biggest graphics card news we've had in a while.
We'll begin by talking about the card that was reviewed here first: the Radeon HD 4890. As great as this sounds, the real-life performance benefits of an overclock are usually limited by the architecture in the first place. Some Notes About Our Recommendations. Best PCIe Card: $400 And Up - Review Tom's Hardware : Best Graph. Honorable Mention:Best PCIe Card For ~$430: Radeon 4870 X2 (Check Prices) Exceptional 1920x1200 performance in most games, 2560x1600 in most titles (some with lowered detail) It's hard to recommend the $430 Radeon HD 4870 X2 when two GeForce GTX 260s in SLI or two Radeon HD 4870 1 GB cards in CrossFire can be purchased for $360.
However, we can't ignore how a lot of folks out there don't have SLI- or CrossFire-capable motherboards and it might not be worth the cost and trouble to upgrade. For these folks, the Radeon HD 4870 X2 gets an honorable mention as a single card, despite its high price. Best PCIe Card For ~$520:GeForce GTX 295 (Check Prices) Nvidia's GeForce GTX 295 sporting SLI-on-a-card is the most powerful single graphics card on the planet.
If you want the best of the best, this is the card to get. Best PCIe Card: $60 To $100 - Review Tom's Hardware : Best Graph. Best PCI Express (PCIe) Card For ~$65: Radeon HD 4670 (Check Prices) Good 1680x1050 performance in most games Once again, we start with the $65 price p oint and ATI's Radeon HD 4670. The Radeon HD 4670 is vastly superior to slightly cheaper cards like the GeForce 9500 GT and Radeon HD 4650 because its complex architecture and fast DDR3 memory allow it to deliver remarkablef performance at this low price. Its closest competition is the GeForce 9600 GSO, but for $15 more, we don't think it's worth the difference, especially with the superior GeForce 9600 GT available at virtually the same price.
The Radeon HD 4670 is also notable because it's the only card in our recommended list that doesn't require a power connector. Best PCIe Card For ~$80: GeForce 9600 GT (Check Prices) A slim $15 spread gives us just enough room to recommend the GeForce 9600 GT, which offers enough performance over the Radeon HD 4670 to justify that price increase if you have it in your budget.
Best PCIe Card: $120 To $200 - Review Tom's Hardware : Best Grap. Best PCIe Card For ~$130 : Tie GeForce 9800 GTX+ / GeForce GTS 250 (Check Prices) Good 1920x1200 performance in most games, some with lowered detail Would a rose by any other name smell as sweet? Sure, as long as the frame rates stay the same. Although the GeForce GTS 250 is a re-badged GeForce 9800 GTX+, the falling prices have kept this older, but still powerful graphics technology, very much in the game.
Radeon HD 4850 (Check Prices) The Radeon HD 4850 hangs in there, competing with the GeForce 9800 GTX+ / GeForce GTS 250 twins at the same price point. Best PCIe Card For ~$160: None The $160 price range sports a number of attractive cards like the 1 GB Radeon HD 4850, the 1 GB GeForce GTS 250, and the Radeon 4870 512 MB. Best PCIe Card For ~$185: Tie Radeon HD 4870 1GB (Check Prices) Good 1920x1200 performance For about $25 more than the 512 MB version, you can have a full 1 GB of video memory on your Radeon HD 4870. GeForce GTX 260 (Core 216) (Check Prices) Conclusion - Review Tom's Hardware : GeForce GTX 295 Vs. GTX 275. More than anything, this was meant as a purely academic look at Nvidia’s SLI technology—to compare SLI across two cards to SLI running on one card. We suspected that the PCI Express throughput afforded by two x16 slots would emerge as a slight advantage over a single board with two GPUs running in one x16 slot. In many cases, it looks like we were right, even if the explanation can’t be solely attributed to PCI Express bandwidth (there’s also the nForce 200 bridge chip and its features to consider, along with the different timings of Nvidia’s SLI link between the different card combinations).
Given the shortage of GeForce GTX 295s in the channel right now, we thought it’d be interesting to see how closely the performance of a GeForce GTX 295 could be matched by two GTX 275s. And the answer, given the GTX 275’s rather substantial clock speed advantage, is that you’ll quite easily outmode a GTX 295 using a couple of 275s—often with frame rates that are 10% higher or more. Best PCIe Card: $200 To $390 - Review Tom's Hardware : Best Grap. Best PCIe Card For ~$260: Radeon HD 4850 X2 2GB (Check Prices) Good 1920x1200 performance, 2560x1600 in most titles with some lowered detail The Radeon HD 4850 X2 is essentially two Radeon HD 4850s in CrossFire mode on a single card, and it will beat the similarly priced GeForce GTX 280 hands-down.
It will even put the hurt on the new, more expensive GeForce GTX 285. We're still quite pleased that the Radeon HD 4850 X2 can now be found on Newegg for $260. At this price, it's the same price as two Radeon HD 4850 cards, but is more accessible in that it will work with any PCIe motherboard (rather than just those supporting CrossFire connectivity).
Past the point of reason: With exponentially increasing prices over $260 offering smaller and smaller performance boosts, we have a hard time recommending anything more expensive than the Radeon HD 4850 X2.

GeForce GTX 295 Vs. GTX 275 SLI: When Two Are Better Than One : The GeForce GTX 275, launched last month, gives us an opportunity to run some interesting thought experiments using Nvidia’s SLI multi-GPU rendering technology.
You see, the graphics processor driving the GTX 275—a 55nm mash-up somewhere between the GeForce GTX 280 and 260—sports the same configuration found in the company’s GeForce GTX 295 (doubled, of course). By putting a pair of GTX 275s up against a GTX 295, we’re essentially able to test one graphics solution operating over the throughput of a single 16-lane PCI Express 2.0 slot against the same arrangement running across two x16 slots. With all of the core, shader, and memory clocks set to the same frequencies, the only real variable here would seem to be the amount of PCI Express bandwidth available to your SLI setup. In both situations, separate PCBs are attached with Nvidia’s SLI connector. Special thanks to Zotac for sending in a second GeForce GTX 275 for our SLI evaluation.
The Anatomy Of A GTX 295 PWShort's GPU-to-GPU link. Benchmark Results: H.A.W.X - Review Tom's Hardware : GeForce GTX. Here we see the same strange phenomenon, where stock-clocked GTX 275s get beat (fairly badly, in fact), by the underclocked GTX 275s and stock GTX 295. Between those two solutions, the underclocked GTX 275s are faster. Turn up the details and, yet again, the stock GTX 275s pull ahead. As before, the two underclocked GTX 275s outmaneuver the GTX 295. Benchmark Results: World In Conflict - Review Tom's Hardware : G. First, it’s again odd that the higher-clocked GeForce GTX 275 cards lose out to the underclocked boards. Secondly, it’s interesting that the GeForce GTX 295 is outperformed by those same underclocked 275s. We asked Nvidia to help explain what might be happening here, but given the number of variables involved (beyond the obvious increase in PCI Express bandwidth resulting from a move to two x16 slots), that it’d be hard to pinpoint a specific reason.
With a more substantial load applied to the graphics sub-system, the underclocked GTX 275s and 295 even out, while the stock GTX 275s in SLI mode pull ahead by a notable margin. Benchmark Results: Grand Theft Auto 4 - Review Tom's Hardware : Reviews. Benchmark Results: Left 4 Dead - Review Tom's Hardware : GeForce. Holy platform bottleneck, Batman. The only real interesting set of data points come from the GeForce GTX 275s at their stock clocks. Though we’ve been watching these two cards smoke the rest of the pack up until now, they’re bested by the same two boards running slower clocks, even. The same thing happens with anti-aliasing and anisotropic filtering turned on. While we’d expect the frame rates to all be similar (after all, faster GPU clocks aren’t going to help on a platform that’s limited by CPU performance), it’s hard to say why the less aggressively-clocked cards turn out to be faster.
The bottom line here is that, either way you go, Left 4 Dead will run plenty well, even at 2560x1600 and all of the details cranked up. Benchmark Results: Crysis - Review Tom's Hardware : GeForce GTX. Ah, the ultimate yardstick. At High quality settings, Crysis is actually fairly playable at 2560x1600. Above that, it looks like our Core i7 platform is holding back performance, since 1680x1050 and 1920x1200 are quite close.
Nvidia still has a problem at 2560x1600 with 4xAA enabled—we’ve seen this one over and over in a number of different games. Interestingly, the two GTX 275s aren't as hampered at that demanding setting as the 295, though none of the arrangements are playable anyway. On the other hand, you could probably swing 1680x1050 or 1920x1200 and still see reasonable frame rates. Benchmark Results: World In Conflict - Review Tom's Hardware : G. Benchmark Results: Far Cry 2 - Review Tom's Hardware : GeForce G. Without anti-aliasing, Far Cry 2 does a reasonable job of pushing the entire platform—especially at lower resolutions.
We see the two GeForce GTX 275s turning in the best numbers at 1680x1050 and 1920x1200. Moving to 2560x1600, however, the GeForce GTX 295 catches up and passes the cards running at the same clocks. Turning on AA emphasizes graphics power even more. Again, the lower resolutions favor the GTX 275s, and the 295 catches up at 2560x1600. But crank the GTX 275s up to their stock clocks and you witness a substantial reason to go with the two cards in SLI mode. Benchmark Results: 3DMark Vantage - Review Tom's Hardware : GeFo.
