If the 660 is cheaper, then go for that as it is faster than the 7850 at stock speeds and has some advanced features like CUDA and PhysX, but if you are confident in overclocking, then the 7850 will smash the 660. In all honesty both cards are fine, I'd say go with what ever is cheaper, and neither of them should bottleneck the CPU.

The GTX 660 is more comparable to an HD 7870 in terms of performance and price.

The HD 7850 still remains an excellent card, you can get really good 2GB ones with great non-reference coolers @ around 190$ , the 660 is about 230$ and the HD 7870 is about 240$.

The HD 7870 & 7850 have a slight advantage due to their larger memory interface, while the 660 is slightly more efficient and supports Cuda + Physx.

If I were to get a 660 I'd go for the Asus model, it costs the same as a regular model but it runs cooler, quieter and overclocks better.

If I were to get an HD 7850 or HD 7870 I'd get any dual/triple fan model from Gigabyte, MSI, Sapphire, Asus or XFX .

both are great cards, but if I choose one... i stay whit the AMD 7850 all the way

the 7850 2GB is the winner to me above the 660 2GB

  • AMD 7850 - 2GB GDDR5 256bits
  • gBANDWIDTH = 170.2 GB/s
  • gSHADERS = 1024 unified
  • gCPUoc = 1050 mhz
  • gMEMoc = 1330 mhz (x4)
  • gPIXELfillrate = 33.6 GP/s
  • gTEXTUREfillrate = 67.2 GT/s

I was recently in the same boat. deciding between those two cards. I ended up going for the 7850 from Asus, reason being is that it was a whole lot cheaper than the 660. After having played with it I am a happy chappy =). But I think they are both really good cards!
