Exactly what it says above, I am looking to get a new graphics card which will keep cool as well as perform in high-ultra settings on new(ish) games such as Borderlands 2, BF3 and some future games at high FPS. This is the GPU I have currently- http://www.scan.co.uk/products/2gb-xfx-radeon-hd-7850-core-edition-4800mhz-gddr5-28nm-gpu-860mhz-1024-cores-dvi-hdmi-mdp-plusfree-g, My budget will be £260, I dont want to breach £300.

The CPU I have is the FX6300 overclocked to 4.1Ghz
