if everybody is going sli/xfire for the long term then they'll almost certainly come out with solid/stable drivers for it... at least you would think that they would...
I just got back from best buy. I figured, "what the heck, maybe newegg is out b/c best buy got all the good video cards." wrong-o, moosebreath! they had zero (0) 8800gt's, they had zero 3870's, BUT, they did have a 7300gt 512mb for 149.99...man, that was tempting... the sales lady told me that they don't stock the 3870 at that store but that she can get me one...for 399.99!!!!! I almost killed her, but I figured that I'd have a hard time explaining that away as "justifiable homicide". Oh well, at least I still have the best buy coupon...
