Quote:the highest clocked 3920xm/3960xm which make a mockery of even the i7 3770k.
The thing is, that isn't the best desktop processor. If we were willing to spend large amounts of money on a desktop, we'd get a better processor than you can in a laptop.
Quote:as you can clearly see from this Notebookcheck chart, the 7970m Crossfire blasts away even the GTX 590 (Dual 580's)
a) The 590 is not equivalent to two 580s in SLI as the two cores are underclocked to function without overheating on a single card.
b) You're comparing hardware from two generations.
c) Non-M 7970s in crossfire will beat 7970Ms in crossfire. Also I haven't seen many Quad crossfire/SLI capable laptops with 4 7970s or 4 680s. In fact I haven't even seen any with Tri Crossfire/SLI of even the M variants.
Finally, I've thought of another general desktop argument (if money isn't something we care about):
Not seen many LN2 cooling systems for laptops, have we.
