OK guys - I went ahead and ordered a 6600GT card from NewEgg. It was about $8.00 more than other places but I have heard only positives about them and didn't like the look-n-feel of the other places selling for less. That said I am still on XP SP-1. Should I go ahead and install SP-2 before I swap out the card or does it really matter? I am assuming that the card will come with instructions on updating the BIOS and other variables? Thanks again for all of your input.
