Making one PC out of two advice needed.

Right, I have two PC's I want to use parts of both to make one and sell rest of parts. Here is what I have:

My old PC:
Athlon X2 4200+ 65W
Abit Fatal1ty AN9 X32
8800 GTX
74GBRaptor and 750GB Seagate HDD's
Corsair VX550 PSU
Creative X-Fi

And then I got this one as part exchange:

Q6600
Asus nForce 650i M/B not sure of model
8800GTS 512MB
2X Seagate 320GB HDD's
OCZ 600W PSU


What I want to do is this:
Q6600 of course (overclock 3-3.2 GHz)
M/B- sell both and get a GA-P35-DS3P
8800 GTS 512MB
2X320GB in RAID 0 for OS and applications, Raptor for pagefile and 750 GB for storage/backup.
I don't know why but I prefer VX 550 over OCZ 600W. Also OCZ is 8 months old VX550 only 2 months.
Creative X-Fi

Sell overs on e-bay.


Sugestions, comments, advice welcome!

Good plan.
