Yikes, GeForce GTX 280M, with a G92 core? This thing is no where near a GeForce GTX 280, but the only naming difference is the M. As if the GTX 250 naming wasn't bad enough, they name their mobile chipset even worse.
I think everyone knows mobile chipsets are no where near as powerful as desktop chipsets, but seriously, naming it the 280M is just going to cause trouble. If the mobile and desktop chipsets aren't comparable, why even bother naming them the same? Why don't they take their mobile chipset off the GeForce line? It would make more sense to have different lines for completely different markets. Name it the MForce or something to reduce confusion.
