6 core AMD Istambul UK where to get?

[lordmozilla]

Cant seem to get hold of Istambul CPU's in 6 core. I think its the 2427 that I want, but might go to 2.4ghz depending on the hard drive config.

Where can i get them in the uk? Or at least when are they available? I can only seem to get a soon from scan.

Cheers
Brendan
