I think that the HD7850 will do a nice job for me at the minute (prob the Sapphire) with a nice OC
... I'm building a mid ranged gaming rig, with future proofing in mind - so on past GPU sales experience, will I have to dash out and buy another HD7850 before the end of the year to Xfire 'future proof' my setup or in your experience, will they still be available +2 years down the line?
