I have been doing quite a bit of looking lately for a laptop replacement. I have a Toshiba P4 (it gets HOT) w/a crappy GPU and a pretty good everything else. I.E. I can't game on it so it's useless to me. I'm gonna give it to my mom and buy a new one. I have been looking at the Dell 1705, the AlienWare 15.4" w/ the core duo that starts around $1399, an Acer w/ the x1600 at New Egg that goes for $1069 (that's right, it's a crazy-insane deal...T2300E 1.66 Core Duo, x1600 128, slot-load super multi dvd, wifi, bluetooth, 1 gig of ram, SVideo and DVI out and scored about 3600 in 3DMark 05), and lastly, the HP dvt8000 build-your-own from Costco.com (I'm a member).
Of all of these machines, the HP seems to be the best deal. Intel(R) Core(TM) Duo processor T2500 (2.0 GHz), FREE Upgrade to 1.0GB DDR2 SDRAM (2x512MB), 100 GB 7200 RPM SATA Hard Drive, Super Multi 8X DVD+/-R/RW w/Double Layer Support, 256MB NVIDIA(R) GeForce(R) Go 7600, Intel(R) PRO/Wireless 3945ABG Network w/Bluetooth, 17.0" WSXGA+ BrightView Widescreen (1680x1050), FREE Upgrade to Genuine Windows XP Media Center, Microsoft(R) Works/Money, 8 Cell Lithium Ion Battery, 2-yr Extended Service Plan with HP Express Repair. This is all customizable and this particular build is $1506. The only problem is the 7600 is the only GPU available. It is, however, the 256 flavor. Originally, this machine came w/ the GeForce Go 7400 turbocache so all the reviews are based on that gpu. The reviewers report usability in bf2, fear, COD2, etc. But I'm not sure 'usability' is what I'm after. I have a 7600GT in a desktop that performs nicely but this is not a GT and it's a Go-model.
For this reason, I am leaning towards the Dell 1705 build, but that is about $400 more expensive. HOWEVER, it will be a 17" desktop replacement with a 7900GS which scores around 6600 in 3DMark 05. On the down side, it will be the T2400 Core Duo (1.83ghz) if I want to keep it JUST under $2k. Otherwise it's closer to $2100.
I WOULD go with the 1505 or the AlienWare 15.4 but they won't offer me an x1600 or better. You can get an x1800 in the Alienware machine (I think but it may only be the 17" Alienware that has the x1800 which starts at $100 more) but I'm not really hip to the ATI line so I don't really know what a vanilla x1800 go version performs like. There is also the Acer which is VERY inexpensive and would do what I want it to but it has some knocks as well. It comes w/ XP Home and the screen rez is 1280x800. Yuck. Otherwise, it's a SPLENDID buy.
It seems to me through my research that by the time you get a 15.4 machine pumped up to what you want for gaming, it's $2k and barely has enough video card (the x1600 is great but you will probably lose a year off the end of it gaming-wise compared to the 7900GS in the Dell). So, if portability is not a concern, it only makes sense to look at the 17"ers. They start at around $1100-1200 at Dell and
HP@Costco.com, they come with eveyrthing you want (except RAM...it seems to be expensive but from what I gather, it's very easy to change the ram and much less expensive - plus, you know what's in your machine and it's almost always better than builder's-grade). You get ALOT more for your money and are only adding about 10-15% in size. My 15.4" toshiba is large. This Dell or HP will be larger. I'm fine with this. But it's portable (compared to a desktop), it's powerful, it's a good value, and most importantly, it's exactly what I'm looking for, just a little bigger than I'm used to.
Good luck,
