Dell M1710 versus Alienware Aurora m9700- Help anyone?

Hi all,

I need some advice as I can operate a computer reasonably well but when it
comes to understanding particular components and their speed, and the
technical hardware ins and outs, I have to look to somebody that is more
knowledgeable than myself.

I was looking at the Dell M1710 but I can't see myself using the 1900 native
resolution for various reasons. I've come across the Alienware mentioned in
the subject line and see I can get a 17" with a 1400 res. I know the
picture won't be as sharp, etc, but my question is more speed related...will
this computer be able to handle games such as Oblivion or The Sims 2 with
relative ease? The product detail is as follows:



[1] AuroraT m9700

Processor: AMD TurionT 64 Mobile ML37 2.0GHz 800MHz FSB 1MB L2
Cache
Operating System (Office software not included): Genuine
Windows® XP Media Center Edition 2005 - Without Remote Control or TV Tuner
Chassis: 17" WideXGA+ 1440 x 900 LCD with Clearview Technology -

Aside from Alien not offering bluetooth, how comparable are the
offerings between these two? Especially speed-wise?

Thanks ever so much for any help or advice!
