Ok I have the Hypersonic-pc Aviator EQ7, same laptop design as those shown in the article. My system specs are 2.4ghz(E6600 or 6400 i think)cpu, 2gb 667 mushkin ram via 2 dimms, 1920x1200 monitor, 2x100gb 7200rpm hdd set up in raid 0, dual 7950gtx's running in sli mode, a DL dvd burner, and its runnin windows xp sp2(heard vista wasnt sli friendly yet on laptops..er something like that) with all the updated patches etc. When all was said and done for two year parts and labor/anything warranty/tech service the total price came in at $3800.00
I am stationed in Afghanistan right now and the temps outside reach upwards of 140 degrees ferenheit at times...luckily I live in an airconditioned tent and bought a lian li cooling pad ...the 17in one...the laptop stays on a table and remains relatively cool. I have taken it to the internet shack setup and in there it is small and no ac and gets very hot...hot enough to cause you to sweat just standing there...I would venture to say well over 100degrees easy in the day. Being in that shack is the only time I have felt my laptop might be in danger even with the cooling pad...the mouse buttons on the laptop itself are metalic and when the pc heated up so did the buttons so much so that it was actually hot to the touch(normally I use a seperate mouse but that day I was lazy)...but that is the only time thats been a problem...keep in mind it was hot enough in there for the cooling stand to actually get hot to the touch so I dont fault the laptop it was under stress for well over an hour and didnt fail me...would I do it again probably not but it did last.
As far as gaming..I play Oblivion run at 1920x1200 full everything except hdr lighting...some weird thing with nvidia and not running hdr and anti-aliasing at the same time. So its one or the other and I chose AA. The game runs fine...a little jitter here or there but for the most part runs smooth...keep in mind its a laptop and compared with even other gaming laptops a game like oblivion would bring them to an unplayable crawl at those settings assuming the screen could even handle the resolution. I also played FEAR start to finish at maxed out settings ...even in intense action still ran smooth...tried the benchmark built into fear and a bulk of the fps were above 60fps. I'll run it again and update this post with the stats later as well as the numbers from Company of Heroes internal benchmark, and 3d Mark stats, 3dmark is enroute to me now as I type. I think my system setup would be a better benchmark comparison to the extreme edition cpu you guys checked out...seeing as to how it runs the same os, same speed ram, same vid cards, and slightly less(one step down) cpu...which is upgradeable to a quadcore option through Hypersonic...couldnt spend the extra 700 for it though. I think that comparison on the few programs I have would really show what benefit you gain from the extra cpu speed as far as gaming goes...that and I am personally curious if its even worth the bother upgrading my cpu ever.
I chose a desktop replacement laptop because Im semistationary and with little space of my own. In other words a desktop was outa the question. Also I move around enough between work and hanging out in my tent...its simply easier to move a laptop, power brick, and external mouse ....than a tower/shuttle, monitor, keyboar,mouse, and power cables in one trip or in one regular backpack. Surprisingly I have found no need for a external keyboard...the one provided is actually quite nice on the laptop. Power consumption...yeah on gaming with it unplugged it sux...like 45mins tops...but thats the whole pt of this pc its not a mobile take it everywhere personal planner ...its meant for when you have time to sit down and game for hours....which usually means you are near an outlet. I believe the laptop itself weighs in at 11.something lbs the brick another pound or two, and thats it so prob around 13-15 lbs...not to bad ...if you want portable easy setup gaming.
For what I payed I feel I got an awesome laptop...probably as good as they get for right now.
