Dell xps 410 vs alienware aurora 7500...

[Neuman101]

So im moving into a new apartment and want to get a desktop...Id like to be able to multi-table, run Pokertracker, PAHud, maybe datamine, and do some multimedia things like get a TV tuner...I also like to have some flexibility to add dual monitors in the future...the first system i designed on dell costs 3500...its an XPS desktop, here are the specs...the 2nd is an alienware system which i would have to assume is top of the line or close to it...its costs 4800...

the alien ware also includes tv tuner, Does anyone own one of these aliens and can comment on whether their liquid cooling and acoustic dampening options are worth it?

Also they offer many different AMD x2 athlon chips (4600-6400) and numerous hard drive options...any guidance would be great...thanks
