The AVADirect D900F is the pinnacle of "mobile" processor performance… not by using the fastest mobile processor, but by using the fastest currently available desktop processor. Clocked at 3.33 GHz, the Core i7-975 outperforms any Core i7 mobile CPU by a sizable margin. With one core active, Turbo Boost on the i7-920XM can reach 3.2 GHz, but that's as close as you can get (and the i7-975 can still Turbo up to 3.60GHz). Considering the two processors have the same price tag of $1000, the only reason to go with an i7-920XM is if you want lower power requirements
