Looks good, nice and furute proof with Tri-SLI, (as we knew already) but I didn't know it was that much longer, and under inspection of my motherboard, which is only normal SLI, I'd need a new one given the SATA port issues, I hadn't thought of that before.
I'm looking for a nice card set up, and I think I'll go for two 8800GTs.

£125 each is a bargain and GTXs are gonna be around £215 I think, or that's what I saw some early ones at. When I look for a future set up, I'd need a tr-SLI motherboard and a new PSU, so the money lost from selling my GTs and buying 3 GTXs won't be so bad as buying 2 more GTXs.
