If i get a 9800 GTX should i also buy a Q6600 or something to go along with it? My current CPU is a C2D E4400 running at stock. Also if i do get a new CPU should i upgrade it at the same time with the video card? Or should i do it one at a time(stick in vid card see if it works and then vice versa with CPU). I also don't plan to reinstall Windows and i dont OC just so you guys know.
