I need a bit of help in terms of proper order to go in. My last GPU, 8800GT, died on me so I had ordered a 6850 as well as Windows 7. I'm unsure of what the proper order of installations and steps I have to take. I obviously want to back up stuff on my computer, but with the 8800GT Windows XP won't load but I can get into safe mode. Do I install the 6850 first, back up everything in safe mode, and then install Windows 7? If anyone can give me a run down of the order I'd really appreciate it.
