Buying a CPU

Thanks for the replies. I was hoping a new CPU would hold me off for a while until I can upgrade. I've already been looking at an AMD Phenom ll X6 1055T Black Edition.Since my motherboard is soooo old, I'm gonna have to buy another one,and then I'll need some DDR3 RAM. Hopefully I'll be able to have a kick a$$ computer for under $800. Thanks again.
