Get the 5850 for that resolution it will play all games on high but it wont max games like S.T.A.L.K.E.R Call of prypiat or Battlefield Bad Company 2. What is your budget or are you building a new system?
$150 - $300. I'm looking to save as much money as possible and not pay for something I don't need.
Would a single 5770 suffice or should I up it up to a 5850 for 1680x1050?
I'm tempted to get a 5850 for now, and use Crossfire with another one in the future when required (and cheaper).
Would that be ideal over buying a single 5770?
