Ehhh, if you have enough money to SLi two 8800 Ultras, I would wait. From what I've heard the new g100 core from nVidia is coming out 2nd quarter of 2008. So if you think you can hold off until Spring, I definitely would. Seeing such a huge jump in performance from the G80 to G92 cores just makes me wonder whats around the bend. I say wait.
