Hi all, I'm currently deciding between the 7950, 670, and 7970, with my main dilemma being whether 2GB of VRAM will be enough.

APPROXIMATE PURCHASE DATE: Within 2 weeks

USAGE FROM MOST TO LEAST IMPORTANT: Games: A wide variety, will be playing the most demanding games though.

CURRENT GPU AND POWER SUPPLY: 6950 2GB, XFX 850W

OTHER RELEVANT SYSTEM SPECS: i5 2500K

OVERCLOCKING: Yes

SLI OR CROSSFIRE: Yes, will definitely be looking at this in the future

MONITOR RESOLUTION: 2560x1440

Thanks!

I encourage you to check the benchmarks that Anandtech haad recently in a review of the 680 Classified, a heavily tweaked 680. It's important because it shows two things: (1) the effect of new drivers on both sets of cards; (2) the limitation not only of the quantity of VRAM, but of the bus width, at high resolutions. Anyway, you should read the whole review, which is informative, but also check out the benchmarks here: http://www.anandtech.com/show/6096/evga-geforce-gtx-680... and http://www.anandtech.com/show/6096/evga-geforce-gtx-680...

For the most part that first page shows AMD-favoring games, and the second shows nvidia-favoring ones. But while the gaps are relatively small all around, you can see that the 7970 and 7950 are relatively better at higher resolutions--they have larger advantages or narrower disadvantages than at lower resolutions.

The 670 isn't a bad choice either--people make too much of the 3GB of VRAM for current gaming even at high resolutions, and it's more efficient in all games and still just better in some games. But I'd still go for the 7970 for a few reasons: it's more overclockable; it's best at those higher resolutions; and the RAM and RAM bandwidth will be an issue faster (that is, sooner--for games coming out soon) at higher resolutions.

Beware of the noise levels on the MSI 7970 Lightning. It's more than twice as loud as the MSI GTX 680 Lightning (+10 Dba doubles the perceived noise level). That MSI GTX 670 Twin Frozr III will be MUCH quieter and perform for all intents and purposes as fast as the 7970. Plus you'll get Physx, Adpative VSync, FXAA, etc.

52 Dba, according to TechPowerUp, louder than a GTX 480 and almost as loud as a 6990.

vs. the exact same cooler on the MSI GTX 680 Lightning, only 36 Dba.

I actually think that 670 is mis-labelled and actually has the Twin Frozr IV cooler on it. It looks exactly like the one in the TechPowerUp review, 37 Dba in load.

Yes, and see this: http://www.guru3d.com/article/msi-radeon-hd-7970-lightn... So I think that techpowerup result is an anomaly/outlier.


Thanks for confirming that :) 

Anyway, it's pretty much down to the 670 vs the 7970...

Any last opinions, I'm leaning towards the 7970, but am not sure about the whole adapter issue :(
