I don't believe in a "where I'm purchasing everything". You're not going to get any deal like that unless you have a Microcenter near you. I am telling you, 6 cores + a high quality ASUS M5A97 (which is like the ASRock 970 Extreme3 in features and price) for $200 is a steal. Get it while you can. NCIX is a reputable Canadian retailer that recently expanded their base of operations into the US. I recommend them often. I also recommend splitting between different retailers for the best deal unless one retailer can price match everything (as with retailers in Canada).
There's nothing wrong with the CX 600 V2, just that it's inferior to the OCZ ZS 550W - which has a larger 12V rail, higher efficiency (CX series is barely 80+ ready) and better quality all-around - for less cost. I find it hard to recommend Corsair units nowadays because there are competitors and Corsair overprices a lot; the CX is their low end unit. I think longer 3 year vs 2 year warranty too on the OCZ.
EDIT: Ok I'm wrong about the 12V rail as the CX 600 V2 is slightly bigger but the ZS 550W probably gives you more headroom. I know this because a review found that the ZS 650W could supply up to 750W safely and 780W before shutting down protectively.
