Building a New system, need suggestions, comments etc.

Hey guys

As the tittle said i'm building a new rig. It's ganna be used for gaming, sound editing, encoding/decoding, and maybe lightwave/3dmax etc.
I'd like to say it's going to be used for applications butttt then i'd be lieng.
It's probably going to be 75% Gaming, 25% Apps/school etc.
I will be overcloking the system and I will be matching the Vid card (SLi) once the price drop and more games support it.

I need a little help deciding on some of the specific parts. Red means its the one i'm thinking of going with, the rest are the options available to me.

PLease correct me if i made a mistake or if a better option exists.

Take the 250gb Seagate drive at 1.5GB/s, unless you really want to pay the premium price for the WD Raptor. Not really sure if the performance gains outweigh the additional cost. Skip the lightscribe, and take a look at the Sony DRU-810A. Between the two CPUs, I'd go with the 4200 and spend the savings elsewhere, perhaps the monitor. Seems like most tend to favor Viewsonic for gaming, but there are others like the LG 1981Q.
