I have an Acer Aspire laptop 7520 it has AMD - TK-55 1.7ghz mobo. It cannot play games like WOW etc. So until I buy a new desktop I am looking to upgrade this. I was thinking of upgrading my mobo it has a S1(638) socket since it shares memory from the G-card what approach would you guys do on upgrading it? And what CPU would be good I really dont know about the S1(638) Thanks fellas
