This is an IN STORE ONLY deal. I don't have the SKU to hand (but will post later) and I can't find the item on the PC World website but it's the same card as here: http://www.macwarehouse.co.uk/catalogue/item/A0221892
When I was in PC World Doncaster today and picked this graphics card up for £9.97. When I got mine about 3pm, there was at least about 15-20 on the shelves.
Obviously this card won't win any awards and probably won't play the latest games but I thought It had to be an improvement over my old ATI X600, especially as it's Vista & Direct X 10 compatible.
