I must admit, I lol'd at deep breath.
It's a very wierd problem that, I've had one or two like that before where I couldn't really trace the cause. I once ended up changing the motherboard, CPU, hard drive and IDE cables just to stop my Windows OS constantly corrupting. I had them spare so it didn't cost me anything. It also worked, which was nice.
Why can't the manufacturers just make things that work.
Crysis arrived yesterday! Getting it to run was a right old laugh. I can't get any nocd cracks to work, but it's very fun! Running it at 1920x1200 all settings medium with AA turned off. Might try low settings and experimenting with AA though, things in the distance are often hard to make out, and I believe that's what AA sorts out?
I really fancy going crossfire but I've heard so many stories about issues with rubbish ATI drivers in the past, and seeing as the 5830 is still only on 10.2 I'm not feeling very good about the prospects....
Mind you, if it's true that 10.4a will support the 5830, hopefully all of the little issues wil be ironed out.
I nearly overclocked it earlier, but changed my mind again. I guessed that Autotune would be a load of tripe, and I wan't happy invalidating my warrenty by doing it manually.
(Although it's not clear whether setting it manually in CCC does actually invalidate warrenty or not).
