I know this was discussed somewhere before, I just can't find the damn thread. I want the 8800gt but I don't want to wait 3-5 weeks and honestly I don't need the 8800gt right away, the ATI will work fine for now. I just need the 8800gt when I switch my gaming needs over to the Mac when I stop using my PC or it dies. Question is, will the 8800gt be available in 6mo time or will they give you an upgrade kit option for a better card if it comes out? How do they work component upgrades, usually released with new machine revisions and thats it until they redo the Mac Pro again?
