Just upgraded my video cards... Do you think it was a good Decision??? I upgraded from two HD6950 1gb to two EVGA GTX 580's. I got them for a price of $460 a piece brand new. "Of course I will be selling my XFX HD6950's" But I want to know.... after all is said and done do you think I made a good decision? I think so....bust still Just want to hear what you guys think.... and yes performance wise there is a huge difference.
