I currently have an ATI 4850 1gb card, and im thinking about the following options (prices are from canada computers):
1) ATI4850 1gb crossfire - $132.99
2) ATI4890 1gb - $199.99
3) ATI5850 1gb - $336.99
In terms of performance from what i've read, 5850 (has dx11) > 4850 crossfire >= 4890
However, taking into account of the price, i'm leaning towards buying another 4850 card and crossfire it.
Any thoughts?
