I'd like to purchase a good rpg game for my laptop. I'd like something with decent graphics, not sure what my cpu can handle though? The specs are:

Model: HP F750US
AMD Athlon 64http://www.microsoft.com/isapi/redir.dll?prd=ie&ar=hotmail X 2 Dual Core TK-57 Processor 1.9GHZ
120GB hard drive
2GB RAM
NVIDIA GeForce 7000M Integrated Graphics
Vista Home Premium

Suggestions?
