Needing a good cpu to run Battefield 3
Picture of mother board - http://postimage.org/image/k3c4ryfdn/db408f9b/
Processor-AMD Athlon(tm)II x4 630 2.80 GHz
Power supply-Seasonic M12II 520 bronze 520W ATX12v
Graphics card-Radeon HD 7850 1GB 256-bit
operating system-windows 7 64-bit
Also my computer says i have 4GB's of ram but only 3GB's are usable so i probably need more ram, whats some good brands? Would i need to upgrade my motherboard along with a cpu upgrade?
