Ok so the first question is can you run a crossfire configuration with 2x2600 cards? If you can what kind of performance should you expect, is the performance worth cost. I have a Saphire X1800XT that has suffered some damage (been to RMA twice) and still not fixed. I am looking at an affordable upgrade, that will let me play games and work at 1600x1050 resolutions. Any info would be appreciated.
