Lol ! What a good joke !
I think you don<t know only one thing about portable computer so let me explain the base of this parallel computer world.
First, a mobile server doesn't exist. I never saw a laptop with a dual-core Opteron in it.
AMD Athlon 64 FX processors is a desktop chip. Never put this in a laptop : it will overheat. Only crazy people/manufacturer do this for fun or to "fourrer le monde" in french ( means to laught or to make buy something very poor to people ). This processor is worse than a Pentium 4 HT in a laptop.
Then, if you want to play, Sempron is really bad.
NEVER take an integrated graphics controller such as the Intel GMA or ATi RADEON XPRESS 200M ( or X200 ). This kind of controller delivers very very bad 3D performances and it steals up to 224 MB of the system RAM --- The PC runs slowlier.
ALWAYS go for a mobile processor like the AMD Turion 64 X2 or the Core Duo ( I prefer this last, I've read some pre-reviews of the AMD Turion X2 and it seems to delivers worse performances than the Intel's baby ). Don't go for the AMD Turion 64 or the Pentium M : already obselete. Mobile Sempron and Celeron M are made for basic utilisation like e-mail and web surfing.
ALWAYS go for a minimum of 512 MB DDR2 RAM ( 1024 MB is more recommanded to play games ), dedicated graphics controller and for a model that has the highest nomber of external ports like a Digital Media Card reader, at least 3 USB Ports, VGA-Out, S-Video-Out, etc.
NEVER go for a Pentium 4 ( even mobile ) in a laptop. It uses too much batteries and its termal dissipation is very bad ( heat a lot ). Overheats with a Pentium 4 are frequent ( just look at an old HP Pavilion zd8000 ! ).
So, my best choice for a gaming notebook is the Dell XPS M1710. Core Duo, 1 GB of RAM' nVIDIA GeForce Go 7900 GS/GTX ( I think it's GTX ) and all the best Dell stuff.
But of course, it depends of your degree. If you play games occasionnaly like once a week, don't go for a XPS ! My baby - a Dell Inspiron 6400 - configured with an ATi Mobility Radeon X1400, 512 MB DDR2, TrueLife display, 80 GB @ 5400 RPM HD, Windows XP MCE, DVD Burner at 1200 $ U.S. is more than correct. Or for a better visual experience or for a little bit more high-end laptop, the Dell Inspiron 9400 configured with the same configuration of my baby but with a 17" display and a nVIDIA GeForce Go 7800 can be better to run futur game at a better graphics level.
But for me - an occasionnal gamer who plays Need For Speed or Tiger Woods PGA Tour - an ATi Mobility Radeon X1400 is more than good !
All computer that leave the manufacturer today should be able to support Windows Vista.
The Pentium M Yonah is pin-to-pin compatible with the furure Intel Pentium M Merom ( 64 bits - dual-core - SSE4 instruction sets ) si IF ( and it's a very little probability ) 64 bits applications make a very big leap into our house, this can be good for a future processor upgrade to take the advantage of the 64 bits.
Any other laptops with a GPU like an ATi Mobility Radeon X700/X800/X1600 or a nVIDIA GeForce Go 7600/7800/7900 can be a very good buying.
So I leave you with this !
