I have a Athlon 64 x2 running at 2.8ghz with 4 gigs of ddr2 pc-6400 memory. Right now I am using a POS Radeon x1300 for graphics, I was going to get a Radeon 4850 to upgrade. For the CPU I have though would that be too overkill? I plan on playing the new Brothers in Arms and Far Cry games, will this setup have enough steam to run them?
