Don't forget that the X1300 XT is not really a faster X1300 at all. It's just a rename for the X1600 Pro, to keep that going after the X1650 finally was ready; and the Geforce 6600 Vanilla, was always a slow card, including the BFG version called an "OC". which didn't come close to what a standard 6600 GT was capable of (I have had one of each, and the BFG version of the 6600 LOOKED good, with a much more efficient heatsink/ fan assembly than the one used by the patterning version (memory lapse, can't recall the actual name for the Exemplar Cards) of the GT model.
