He meant the desktop variant 7900 gtx.

the 7950 gtx go does out perform the 7900 gtx go. look up 3dmark06 benchmarks.

"...8800M GTX fogged to Dell..."

"...or is this "GTX" is going to be "GTX" by name alone? µ"

Probably --remember that the performance of mobile GPUs is usually a tier or two behind the similarly named desktop counterpart; ie, a GeForce GO 7950GTX does not outperform a 7900GTX, despite what the naming conventions would have you believe.
