Looks like there is something wrong with this computer. Again :'( Just tried the benchmark in Dirt 3 which was running soooper smooth before. Average was 34, min 18. Definitely not right.
Hopefully software rather than hardware, unless the dying PSU damaged something.
I'm jealous, I want it, but I've heard It really buggy at the minute, I've gone on about it that much that I have a sneaky feeling my girlfriends got it me for Xmas, so I don't want to buy it yet just in case, really want though :'(
