Had my Sapphire 9600Pro from Overclockers.Co.Uk. Its the genuine article
with 400/300. Its £141 including VAT. Just took a look for you and
unfortunately they're currently out. Nice system BTW.
I got a Saphire 9600Pro Fireblade from kimplett a couple of days ago. £150
delivered. The Fireblade is guarenteed overclockable by Sapphire, if you
are that way inclined
Not tried myself yet.
