My parents just bought me a new computer and it comes with the HD 7570. I have been given a choice of these two graphics cards to replace the slow 7570. So first off the gtx 550 ti is made by evga and is only $100 and i can go out and pick it up right now from bestbuy, or i can get the HIS HD 7790 off of newegg for $135.
So which will give me more performance for the money?
Second, is a 460 watt psu enough to run these cards?
I know these are not the most powerful cards, but i already have a good gaming computer, i just need this one as a back up to take to friends houses for lan parties since i hate moving my good computer, so how well will these cards run on more demanding games like crysis 3, far cry 3, and Battlefield 3 on a 1440x900 resolution with a FX 8140 processor?
