2xHD 7950 vs GTX 670

[willtrking]

Looking at building a new PC and wondering whether I should pick up 2 HD 7950's and run them in crossfire or just one GTX 670?

Thanks!

Just wondering how you came up with those as your two choices for your gpu/'s. Two 7950's costs around $700 while one 670 costs <$400. Obviously two 7950's are going to give better performance than one 670, but it is probably not worth it. If you are gaming at 1080p, then one 670 will be more than enough for the next year so and you'll be able to max out just about any game. If you are gaming at any higher resolution or more than one monitor, then I'd recommend a 7970 which is usually around the same price as a 670.

I agree with above comment.I go for one card either way will work fine.

Is this really a question? Obviously the 7950's. One is about as strong as a 670. This would be similar to asking if a 1000 pound horse could pull a cart better than two 980 pound horses. One 980 pound horse would barely be slower. Also, you are spending almost twice as much on two 7950's. The 7950's might even offer performance that is similar to a 690.
