High-end Desktop replacement

Last response: in Laptops & Notebooks

I am purchasing a high end desktop replacement laptop, and I believe I have narrowed it down to two options. I am concidering the Sager NP8690, NP9280: 15 and 17 inch notebooks respectively. The first features a mobile i7, the second a desktop processor. I am curious if I will see a significant performance diference between the two processors, I have a 920 desktop box at the moment which performs quite up to my expectations, does the mobility processor take a big performance hit?

My second question concerns the GPUs. Between the Mobility 5870 and the GTX 285m, which has better overall performance, and if so is there a significant diference, the price is essentially a non-issue and the radeon is not available on the 17 inch option?

My final question: do aeither of these laptops have known cooling issues? Power consumption is not a problem, and the room they will be in never exceeds 70 degrees, but the partially enclosed desk may slightly inhibit airflow (there will be several inches of clearance for all side vents, but the laptop will be placed in an alcove of sorts, enclosed on 3 sides.

SAGER NP9280 has a better CPU but it runs hotter because desktop CPUs produce more heat than mobile ones.
But NP8690 has a more powefrul VGA.Also both have excellent cooling solutions.
You may want to look at SAGER NP8760 which is the 17" version of 8690

This is review on the Asus G73H-A2 Which has the Radeon HD 5870m: and advance cooling system.
It has two fans which keeps laptop at a warm temperature, even on the most instense game, with this HD radeon and resolution of this PC you know you gonna play Intense Games On Top Graphic Options
