Help me a choose a gpu for my build please

[Funkhouse101]

Mobo: ASrock z77 oc formula

CPU: i5 3570k

Cooler: akasa voodoo venom multi fan (extremely large)

Plus 7 fans

Case: full tower nzxt phantom enthusiast

Ram: corsair 16gb vengeance

Psu: cooler master m2 1000w

The gpu I'm looking for is something that will play bf3 on ultra and other games fine, ranging from £150- £250 maybe push a little more but rather not, I'm using a 22inch monitor hd.

I have a gpu in mind which is the Gigabyte ATI Radeon HD 7870 OC Windforce 3X 2048MB GDDR5 PCI-Express Graphics Card from overclockers

Any advice on any of my planned system I would appreciate but it's mainly the gpu I'm unsure of

Thank you

Thanks but I think I've decided on the slightly more expensive sapphire series what do you reckon ? It works out around £250

I've removed the links thanks for that sorry, I thought about a gigabyte one initially I've found a sapphire one at 207 pound think its the model below the one I first mentioned Sapphire 11196-09-40G HD7950 3GB Vapox-X Graphics Card, ill take a look at what you suggested though thanks for your help
