The real problem is just like you said, "Is this just a stop-gap?"
Yea, you know, this should have been a dual core GPU, period.
The manufacturers need to stop with the confusing 7950 GT, 7950 GTX, 7950 GX2 all of it. There is only one reason they do that and it is because they want to cash in on the confusion. I guess I can see the GT vs. GTX, but when we start breaking it down to GS, GTO, GT, GTX... come on. Especialy when you can have a 7950 designation but the GS portion actually brings the performance below a 7900 (these are just made up for sake of arguement, I know that this perticular model doesn't have those designations yet)
I kind of got off the notebook topic here, and I appologize for that. If anyone wants to really dig into the 7950 in its own thread I actually sponsered the notebook forum at:
