You're not gonna get a new system for 130. I'm thinking you won't be gaming AT ALL with the integrated GFX on that board so if that's a concern then yes, buy a GFX card. 6770 should be within your budget. Maybe even 6850, that would rock for gaming.
What about AMD X4 640 or Intel i3 530 or any other decent processor in that range? Won't it give me a performance improvement?
