Hello, I got some questions; Is the AMD radeon 7850 2GB enough for handeling games like BF3 and next BF4 at 720p display? Should I wait one or two months more for price drops in AMD's graphics cards, so I can maybe buy an 7950 or 7870? Is the AMD FX-4100 4 x 3.6 GHZ a good CPU for this graphics card (7850) ? Should I get more then 550W for this graphics card (7850) ? Would it make a big difference if I pick this CPU, AMD FX-4170 4 x 4.2 GHZ? Thanks for a response!
