Reviews Word on the street

Radeon HD 7850  vs GeForce GTX 660 

We see very good overclocking potential for GPU clock, which is the best of all HD 7850 cards that we've reviewed so far.

I own both... on my I7 system, i am running the 660 Superclocked signature 2 & on my ALL AMD system, FX6350, I'm running 7850 crossfired (1 MSI twin frozr & 1 Asus CU) I picked up the 7850s for $50 & $60 =$110 total, (that was in May) I picked up the Nvidia for $70 (so of these clowns on ebay... price their used GPU's like they are only 1 month off market! you have to edumacate these idiots.... But i have to say... i'm impressed with both setups...(the twin 7850s rock my single 660) but obvious 2 660s would rock the 7850 (basically r9270s) My older system had 560TI with OC'd E8400 (ran pretty well, I was able to pick up a second 560TI for $40) so i SLI'd it....(it would run certain games better, but obviously my limitations were with the processor (bottlenecking) so i swapped it out for my Q6600, (it ran smoother, but for whatever reason my ASUS P5ND couldn't OC that chip, so i tried a Q8200 i had around... same issue) but i gave that system to my nephew... not bad system... Q6600 (stock) 8 gigs ddr 800 ram, 2 560TI SLI'd...
same i got for $90
I got my 7850 off ebay for $80
not really nvidia isnt alway good... they make my games crash a lot so im buying a 7850 now yay
theyre both good so no one wins
when you talk about gaming, nVIDIA is the best, no doubt!
But it really does not matter because the 660 overclocked will again pass it up. The price of the 660 is also better than the price of the 7850, So you would be dumb to by the 7850 unless you could get it for $150. But really the 7850 is not to much faster than the 650 Ti, I am going to replace my 650 Ti with a 660. Great prices on them now
HD 7850 is better for gaming.
and GTX 660 has dropped its price to 180 USD...
660 wins stock 7850 wins when OC'd
