Hi, Which of these two cards perform better? Benchmark reviews says 660 has a better frame rate than 7850 in all games.But,some people say 192 bit memory is bottleneck for several games if choose 660.Since,im not interested in overclocking,im planning to choose 660. In india these two cards lies in the same price range. 7850-15k 660-16k Also if i choose 7850 will there be any added advantage over 660 than the memory bit? Please help me.
