Re: Possible to SLI 6800 Ultra with GT?
Mixed vendor SLI only works on the same type of card - 2x 6800 Ultras, GTs, etc. You could sell your Ultra and purchase 2 6800 GTs or 1 7800 GTX. I'd do the latter, then save up for a second GTX. Prices should go down for retail purchases, or you could save even more by picking one up second hand from someone who will sell it to buy a G71 or Radeon X1900.
