I had almost sorted my spec, down to the last component, and then OcUK went and threw a spanner in the works by lowering their prices today 
The choice is between:
Gigabyte GeForce GTX 560Ti "448 Edition" WindForce 3X OC 1280MB GDDR5 @ £167.99
http://www.overclockers.co.uk/showproduct.php?prodid=GX-094-GI
and
VTX3D HD 7850 2048MB GDDR5 @ £179.99
http://www.overclockers.co.uk/showproduct.php?prodid=GX-005-VX&groupid=701&catid=56&subcat=411
Originally I was going to go for the 7850 option, but then the 560Ti 448's price was lowered, and budget is a big one, so... Hmmmm!
It's mainly a gaming system, mostly playing ArmA 2 and ArmA 3 when that's released. I'd also like to play most new and upcoming titles at medium-high graphics settings.
My basket looks like this so far:
Intel Core i3-2120 3.30GHz (Sandybridge) Socket LGA1155 Processor - Retail - £86.39
Gigabyte Z77-D3H Intel Z77 (Socket 1155) DDR3 Motherboard - £84.98
Antec 300 Three Hundred Ultimate Gaming Case - Black - £39.98
Corsair XMS3 4GB (2x2GB) DDR3 PC3-10666C9 1333MHz Dual Channel Kit - £22.99
