Ok you get your SLi GT's with a total of 512 RAM, I'll keep my 768 Ultra until the new 9800GTX pops out. I can't help you to realize it doesn't matter how fast your SLi setup is if you don't have enough VRAM to support the textures with AA/AF enabled at higher resolutions.
It's like having a Q6700 w/2 15k raptors on a SCSI card, the sweetest SLi setup on the planet, and 512 MB of RAM.
It's a damn fast setup, but as soon as you have used that RAM you might as well be on a PIII-850 for all the performance you are going to have.
That's why the majority of the tests at high resolutions are w/o AA/AF enabled.
If you don't need or like AA/AF at high resolutions, and aren't interested in the 9800 series coming out shortly it's a great card to get.
