I'm running the same processor, Phenom II X4 965 black edition 3.4GHz, due for an upgrade as well. Just swapped my dual HD 5770 cards for a single EVGA GTX 970, boy that alone was an insane difference. :) I'll probably upgrade the mobo, ram and get an Intel chip in the next few months or so to complete it. But like MFTDarkEagle said it'll be a big difference.
