7870 HD vs gtx 660 Ti

[hirajhil]

Hi, I am looking for your opinion regards 7870 HD and GTX 660 Ti. Which card should I buy for best performance?

And Radeon 7870 HD has got a wider bus of 256 bits, is this significant? And nvidia comes with Physx and are there any adavantages for that?

Both of them are almost same in performance, amd case has better bus width means its memory will work at better speeds since the memory clocks are almost the same in both the cards. For me physical doesn't make much of a difference.

660ti is faster in performance, its more in line with a 7950. Having the faster memory bus only really gives an advantage in resolutions higher than 1080p, and when using more than 4x AA, which neither card could handle well anyway in most games, so its a non-issue. If you were looking to run higher than 1080p you should be looking at a faster gpu than either of those anyway.
