Cf 7850 or gtx 670 or gtx 680?

[gab10101]

As of now I have 1 hd 7850 and I can get another for $280 aus. Alternatively I can get a gigabyte gtx 670 for $533 or a 680 for $750. Is it really worth spending the extra $200 for the 680 or will I get as much power from 2 7850's? Also there is an asus gtx 670 for $588.

Btw the both the 670's are overclocked.

Just buy a second HD7850.The two cards in crossfire will often outperform a GTX 680!And you'll also save quite a bit of cash.

If you already have something in mind about what to do with your 7850 (like selling it for not much loss), I would suggest the 670 which is best $-performance wise. It also open the possibility for a much more powerful dual card configuration (SLI) if you feel so incline in the future.

But if you can only dispose of the 7850 at a considerable loss, then I guess considering a 2nd 78509 for CF is not bad idea at all.

How much more powerful is the 680 compared to the 670?

Not by much. Please check the benchmark results between a 670 versus other cards (including the 680) here:
