What is the AMD equivalent of GTX 660?

Thanks XD

But 7850 outperforms 660 as for the last drivers.

AMD HD 7XXX series is not as good in DX9 games, but its great for DX11 games. The nVIDIA GeForce GTX 6XX series does have a memory bandwidth bottleneck in games when enabling 8x or greater MSAA.

Yup, the PS4 is rumored to have an AMD HD 7970 Mobility graphics card = AMD HD 7850 = nVIDIA GeForce GTX 660. If your not upgrading but buiding a new PC, PS4 is a good alternative. To build a PC equivalent to PS4's specs would cost more than 710 USD. PS4 is rumored to cost in the range of 400 USD to 530 USD. The savings can be used to open a fixed annual IRA or interest rate annuity since the age to collect social security keeps increasing.
