I have P5N73-AM - Asus mother board and Intel(r) Core(TM)2 Duo CPU E7300 @ 2.66GHz processor. I want to start gaming again but I don't know if this motherboard and processor are good enough. Also I wanted to know which graphic card will be compatible with my Motherboard and processor. Please advice me on my motherboard, processor and which new graphic card is advisable?
