I currently have athlon 64 x2 3800+, radeon hd 6570 and 4gb of ram on a delta 250w psu. The processor im looking at is the athlon 64 x2 5600 2.9ghz brisbane. It has a tdp of 65w and my current one has a tdp of 89. I found the processor for 30 bucks and i can play bf3 finally with the upgrade. Thanks in advance
