In the UK, on "ebuyer", the 6950 is only £198 i've noticed, you get free delivery too. Thats' the top of the range for your money, if you want something much cheaper then get the 6850 that's what i've got.
is that a micro atx motherboard you have there? asus p8z68? I wonder if doing say two 6850's or 6770's in Crossfire would be good. Lmao Signor that graphics card takes up three slots, i don't think i've seen one like that before. But the 6950 on ebuyer by powercolor is just £197 that's £227.
takes up 3 slots but the cooling on it is amazing, the only 1 which gives similar results is the twin frozr from MSI, able to have it unlocked and overclocked and still staying ~35 degrees is pretty nice
