you couldn't possibly crossfire 4 of these cards...or could u?
Possibly, but it would require rewriting the drivers to support it, just like it was hacked into the X700 and X300.
Heck they were able to make it work in a fashion on the R300s, so even if these are RV3xx of some type (R9600 or X600) it would be something that would require rewriting of the drivers to make work smoothly.
Sorry to spoil the fun but there is no crossfire tab.
So? Nor is there one on the X1300, X1600, HD2400 or HD3450 yet they all do Xfire through the PCIe bus.
Don't try to spoil the fun if you don't even know that.
