I have currently found 2 diffrent PCs, which i would like some input on.
They will be mostly used for gaming. Battlefield 3, Diablo 3, Starcraft 3, Alan Wake, Max Payne 3 etc. So newer titles, and would like it to be able to run most games at high or ultra settings. And would also like it to be as the title says, future proof, as in, it will run games fine for at least 1-2years without much issue. Of course im aware i might have to upgrade the graphics card at some point, but as long as the rest is fine and can do what it should, then i am happy about it.
in the first one, replace the 570 with a HD7850. same abilitym far less power usage, with that you can step down as low as an Antec 380W PSU for a single card.
in the second one, replace the PSU with one of similar wattage from antec, seasonic, corsair, pc power and cooling, or xfx
Sadly I dont have any option to change the PSUs at all. I can however change the GFX in the first one as you suggested.
But I have to admit I have had nothing but problems with ATI drivers in the last 3 years ive been using them, which is why i Picked the 570.
