New system build, quick questions.....boyah

This is going to be my first complete system build, over the years the most I've done is a few upgrades to existing computers. I looking into customer computer builders because I did not want to use proprietary parts. At the end of the day building the system I want ends up being over $1000 less than purchasing it.

So skipping to the specs: http://secure.newegg.com/WishList/ [...] er=6715174


That should be the most up to date wishlist info. Any comments on the config would be appreciated.
One issue I'm having is that the Asus P5e Deluxe has issues with ram over 800mhz. All of the posts that I have read are dated july 08 at the latest and claim there isn't a 4gb kit on the qvl. Last night I checked the qvl and it listed a corsair 1066 4gb kit. So is it logical for me to assume that there was an update making the 1066 ram a non issue (I doubt it, I'm not that lucky)? I like the board a lot and it plays well with the rest of the components but if it comes down to it I'd rather swap it out than have to play with ram for all eternity.

Second issue, not really an issue just confirming something..... will the Thermalright Ultra-120 CPU Cooling Heatsink http://www.newegg.com/Product/Prod [...] 6835109125 work with a q9550, I'm thinking yeah but just want to be sure. I wanted to overclock the processor from stock to around 3.0-3.2ghz. The overclock was the thing I was supposed to be scouring the internet for information on. Thanks in advance for any help.

+1 to everything

9550 (8.5x) -> 400*8.5= 3.4Ghz (that's 1:1 with DDR2 800). 800 memory will do fine. I would avoid the Dominator series and stick with the XMS DHX series. Like this or this. If you're spending so much on a top-of-the-line rig, why not go for a better cooler? My suggestions:

TRU
TRUE
Xigmatek S1283

Edit: Good call on going the ATI 48x0 route.
