Gigabyte GTX 470 SOC

At stores, usually.

EDIT: Sorry for the cheek, but I couldn't resist the smart ass answer... Unfortunately I can't help you. No idea.

www.scan.co.uk is a great place for your area.

this search result should help!

(i'm possibly looking for one too!)

ebuyer.co.uk

overclockers.co.uk

Both very good sites onto which i use on a regulary basis.

Scan/Misco are hit and miss, both ive had missing components and late deliveries. Find their customer support very poor also.

Thanks for the input guys! Only ebuyer had it. I have now got 1 ordered and while I was there it emptied my wallet with a new psu and optic drive on order aswell!! Thanks again
