I'm seriously tempted to do it too... I can't believe the results they get from an £80 chip. I reckon they're gonna sell out PDQ once other peeps get wind of this.
I would need to get approval from my financial controller, but should be getting my yearly bonus soon, which would cover everything I'd need, so she might let me get away with it.
One thing I'd be worried about though is the amount of noise that Zalman hsf kicks out running at full pelt. Don't fancy going down the water cooled route, so would have to be air cooled which is gonna be noisy at that high a temp.
Anyway, from a huge AMD fan, this is damn good stuff!
