I currently own a hpzd7188 with a P4 prescott/desktop processor I believe and go 5700. I will never EVER buy another laptop with a desktop processor in it. Heat issues are a nightmare and gaming is effected by the heat. Lagging on cs:s makes it no fun. Needing to run fans and stupid crap is lame.
Not sure about the price quotes that were posted but the dell quoted was not a 9300 or xps which is the forum we are in so why dont we use AW and others 17inch laptops and I am sure the prices will be quiet different.
So lets look for an AW m5700 with a go 6800 and same specs as the dell I just ordered its 1,457.00 and you get AW's super crappy customer service which has been the subject of many internet posts.
Dell price for a basic 9300 is 1,198.00 with a go 6800. So 257.00 more for uh nothing but to say you live under a rock and dont know how bad AW treats people and all the problems they have with there lappys lately.
Actually though I paid 999.00 for mine and got the 6800 ultra of ebay for 200.00

Oh yeah then I added the accidental damage warranty to my dell because well accidents happen you know

.
So in the end for less the alienware I got the same laptop with a 6800 ultra

and an accidental damage waranty which just may be usefull in 9ish months as I gots butter fingers. Lets not forget about dells coupons and the fact that finding parts is gonna be easier makes it better. Lets also not forget that dell has gotten many positive write ups and awards for customer service, but AW doesnt.
I would also just say anyone buying a laptop for hardcore gaming is silly, I bought mine for light gaming at work and school and at friends houses. for serious gamming I pieced an amd 64 sli system for less than my laptop and it pwns.
