GeForce GTX 670 2 GB Review: Is It Already Time To Forget GTX 680?

Two GeForce GTX 670s In SLI

As you start sliding down the price ladder, adding a second card right away or somewhere down the road becomes a more attractive (and more realistic) proposition. Paying $800 for a couple of GeForce GTX 670s is still a lot of money, but $400 now and as much or less in a few months doesn’t sound as bad.

How, then, do a pair of GeForce GTX 670s perform compared to just one?

At 2560x1600 with graphics details cranked up, a second GeForce GTX 670 can turn marginal playability into a smooth experience. If you’re only gaming at 1920x1080, there’s really not much reason to add a second board. But as you start exploring 30” screens or multi-monitor gaming, a configuration like this makes a lot more sense.

Dividing those numbers into each other, we see that the best-case is Battlefield 3, where a second GeForce GTX 670 nearly doubles performance. Metro 2033 and WoW are both worst-case scenarios in our suite, where the second board boosts frame rates by 72 or 73%.

And now, the title match. Two GeForce GTX 670s against a pair of Radeon HD 7970s.

Five times out of six, the 670s are faster. The sixth is Metro 2033, where two Radeon HD 7970s are about 18% faster. Even in World of Warcraft, though, where Nvidia’s cards are more than 50% faster, performance is high enough on both setups that the experience is fluid.

One thing to keep in mind, though: Radeon HD 7970s are scalable up to four cards (as are GeForce GTX 680s). Nvidia is limiting its GTX 670s to three-way SLI. I don’t see that as a problem, since the market for four-card configurations is diminutive.

Update (5/11/2012): Reader jaquith noticed that EVGA's box art listed four-way SLI as a feature of the GeForce GTX 670. We went back to Nvidia for comment and received word back that the packaging would need to be changed. A short time later, a new message indicated that a future driver will, in fact, add four-way SLI support to the GeForce GTX 670s. Apparently, this is a matter of validation that Nvidia still needs to perform, not a technical issue with the hardware or software.

    Great Review Chris!!

    Though there isn't really a performance hit but it would be great to have seen the GTX 670 running at PCIe 3.0.

    $400 is still too high for me... Waiting for something around $225
  • rglaredo
    I hate Nvidia and their supply and demand game is obvious that they are just holding off the cards to inflate the prices...I'm going with AMD ....because I'm tired of waiting ...I'm not going to wait anymore ..
  • sayantan
    Nice move nV , forcing AMD to drop their prices for entire lineup. A 7970 at $400 would be really awesome...

    The list of games is very unfair to AMD cards. Techpowerup's review, which featured a much longer list of games, had the Radeon HD 7970 faster than the GTX 670 at all resolutions 1080p and higher.

    Nvidia has had a big lead in Dirt 3 and WoW for a very long time. This skews the results.

    The GTX 670 is a fantastic card, don't get me wrong. Just pointing out that it's being slightly overrated here.
