Ahh yeah I remember running into that problem when the BETA came out. Id forgotten all about it, nice one for reminding me
I think Im back to Intel now. Got my eye on either of these:
Intel Core 2 Duo E8400 3.0GHz
or
Intel Core 2 Quad Q8200 2.33GHz 1333FSB
The Quad is £10 cheaper but obviously slower cores. I am going to check the virtualisation support on them now
edit:
The Quad Core doesnt support Intel® Virtualization Technology so thats out then
