Yeah, I'm hoping to get something based on the NForce 3 chipset.
I'm not 100% happy with Asus at the moment, they basically released an alpha motherboard to the public without giving a toss about the enthusiasts who buy the things.
Next thing to do is swap the RAM in my Athlon 3200 system (thank God I haven't sold that system yet!) for the RAM in this one then run it through some heavy duty benchmarks etc.
If it's fine then it's the RAM, if not it's the mobo - I'm assuming it's the mobo at this point...
If it does turn out to be the mobo I'm going for an ABit NForce 3 - different mobo brand, different chipset.
