7790 vs 7850

hey guys im looking to upgrade my grahpics card and was wondering which one of these two is the best the Sapphire Radeon HD 7790 Dual-X OC, 1GB GDDR5 or ATI Radeon HD7850 2GB GDDR5 OC. My psu is only 460watts and my current set up is i7 2600 @3.40 quadcore 6gb ddr3 ram,2tb harddrive so the amount of watts they use is also a factor. thanks

  1. 7850 is better, but the 7790 will definitely work with that PSU.

    The 7850 is faster in many benchmarks, but the 7790 beats it in a few due to newer architecture and higher clock speeds. The 7790 has a TDP of 85W compared to 130W for the 7850 so that might be a big factor when considering your power supply.
