Building my first system and I need some help

[twinshk2]

Well I finally got some money and I am going to try to my hand at building my own system because I heard it's cheaper by a bit. I need a gaming desktop that will last for about 4 years playing the most demanding games on high graphics.

Budget:$2500(With this I can probably buy a factory built one but where's the fun in that )?
I might have to upgrade later so for now my effective budget is around 1800

Power supply: http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=5683590&CatId=2535

It might seem overkill but I might upgrade to Crossfire later.

Would you mind waiting one month for Ivy Bridge to be out? What all is this build for? Just gaming? If you need all 8 logical cores of the i7, I would recommend building something like this:

i7 3770k + p77 board = $480
gtx 680 = $500
Corsair TX850 = $120
WD FAEX 1 TB = $140
Small SSD (40 - 64 GB) for cache = $90
NZXT Phantom Case = $130
8 GBs of G.Skill RAM = $60

For a total of around $1500

I wouldnt use a Kingwin powersupply if you gave it to me. The only 2 power supplies I ever had that didnt last a year were kingwin. Bought them 3 months apart different models, 1 lasted 4 months, the other 7
