Vista blue screened on first install!! Joy! LOL! Took 4 attempts - each time getting a little bit further and hung on the first "performance test". But now it flies!! Literally!!

It hits 5.9 on CPU and RAM and 5 on the DISK - I'm gussing that cos I'm not using Raptor disks?
GPU wise I'm running a PCI Nvidia Quadro NVS280 64MB, so it only scores 2.
Any thoughts on what GPU would be best to get? I'm not playing games but I want to be fairly future proof. High Def movies is a must. I run 4 monitors so I was thinking of getting 2 ATI's (3850) for crossfire but now I'm thinking perhaps a 8800GT for main use and another "baby" Nvidia card for the other 2 monitors (I've always had Nvidia previously). I know these can go SLi though due to the board. I'm guessing SLI / Crossfire is only beneficial to gamers anyway?
