Input on New Machine

[Meeo]

Im currently looking at this list, which is highly similar to another list that was posted recently.

http://secure.newegg.com/WishList/Pu...umber=15999729

Its going to replacing an Alienware Aurora R3 which was very similar in specs, with an i7-2600K, 16 Gigs of Corsair Vengeance., 2 TB SATA II Geforce 560 Ti. I know a lot of people dislike Alienware, but i have been pretty indifferent to them, even after the merger into Dell.

Its been over 10 years since i built a machine from scratch, as i started to dislike DOA products, hence why i started buying pre-built to work machines(LoL they do not always work as intended tho).

I am a 5 boxer (5 Physical machines) i use 2 other machines for Streaming and Capture so i have 7 computers in my room. I will be basically moving my current main machine down into the secondary and rolling off the bottom (Weakest) machine which is a Dell XPS machines from 2 years ago.

I need some considerations regarding what i have listed and if anyone has any other ideas, i am usually open. i have a approximately $2000 US budget range, i do not mind spending less, if i had to spend more i can probably do so ever so slightly. I also do not mind downgrading Processors if a 3770K is overkill.

My Goal is to be able to multi-box 5 WoW or Rift on a single machine, as i would like to start phasing out all the cases i have in my room, not counting the other laptops i also have setup. I have really no clue why i do not just upgrade my current main machine. I guess its more like i want to replace my weakest machines with a better machine to replace my main machine..... i guess

I also apologize for my ignorance in current Gaming technology, i am getting to old to keep up with it all these days, and i know my punctuation and sentence structure is severely handicapped. LOL
