Need for suggestions

They are correct about that ram. That ram is suited for an i7 build. What's your budget, monitors resolution...etc..

Thanks, just edited post.

Preferred websites for sourcing parts ?

for that much money it would be ashame to not go i7. I'm sure Why_Me can copy/paste his i7 build, it's a good one.

^+1

Shopping at different retailers is mild inconvenience, but it does save you a substantial amount of money. This build is a good one...either gtx 275's in SLI or 4890's in Crossfire...you can't go wrong with either vid card imo. This case down below is new to the market, and it's the hottest selling case going atm....and for good reason. Plenty of room to work with, and excellent cooling, not to mention the fans aren't over bearing.

Also if you do a google on "ewiz coupons" or "ewiz promo codes" you can take another $5 - $15 dollars off that mobo/cpu combo down below.

Another ^+1. With that budget, i7 would be a better choice.
That case looks nice; in some ways it looks similar to the CM-690, which has excellent airflow.

So why go with the i7? isnt the AMD one faster?

Certainly not, you may find a stray benchmark or two where the AMD platform will eek out a win, but all things considered the i7 is faster.
