yeah I built this bad boy thinking I could potentially 5 box on it alone iv even got 3 PCIE 16x geforce 8600's on order so i can run 6 displays on it. I did manage to get all 5 accounts open in shat at 22-27 FPS (all windows viewed with 60 megs in mods loaded each) and some pretty high graphics settings. i loaded up keyclone and got them to jump in perfect sync and move around a bit, but it BOSD soon after.

All that said the issue isnt just with multi-instancing. I have set everything back to default and ran around like that on 1 toon and am getting the random crashes / BSOD's
