Laptop World of Warcraft build NEEDS HELP!

It's good enough for playing WOW, however you can get A LOT better for your money.

Gateway® P-7811 FX Edition

That one has a Core 2 Duo @ 2.26 Ghz, 4GB of ram, and a GeForce 9800M GTS (Which is a HELL of a lot better than a 8600M GT). All for $1250, which I think is a pretty darn good deal, especially for a laptop.

Or this one for $1300 with a C2D 2.2Ghz, 4GB of memory, and 8800M GTS:

Gateway P-173X FX Edition Notebook PC - Intel Core 2 Duo T7500 2.2GHz, Bluetooth, 802.11b/g Wireless, 4GB DDR2, 200GB HDD, DL DVDRW, 17" WXGA+, Integrated Webcam, Windows Vista Ultimate

I just noticed that decent laptop gaming is starting to become affordable... isn't it?

EDIT: Now that I looked over the dell website and saw how much it costs to make your configuration, I think it's obvious you should go for either gateway laptop.

I would not touch one of those Gateway Laptops with a 10ft pole.
If you read the reviews, they have serious overheating issues.
Most likely, it will be toast in 6 months.
Mail your PC in for repair, maybe it will be back to you in 6months and it may work for a few more.
(I did seriously look at the Gateways and nearly bought one, but then I read a number of reviews as well as physically examined them. It even felt cheap.)

Yes, The Dell is XPS M1530 Laptops are seriously over-priced.

The Studio Laptops are more reasonably priced and could easily handle WoW.

I'm sure you could configure an HP Laptop as well that would do a reasonable job on WoW.

Why buy a laptop with a Nvidia GPU, since they are known bad and Nvidia wont do anything about it.

these are great laptops that are built well and priced way below dells.
