About to buy a build, input would be appreciated please. (Don't know where this goes)

Hello,
The last time I built a computer was Deceomber 2005, and I have decided that it is time for me to get another one. I have intentionally kept myself out of the loop because it depresses me to see how fast upgrades become available, so the past month has been frantic researching on my part to try and catch up. Finally, yesterday, I have made what is hopefully my final decision on what components to use. I am posting here to see if there is anything I have overlooked (compatability and/or performance wise). Anything that you notice or any suggestions you have would be helpful, thank you.
Note: This will be primarily for gaming, so I was set for the longest time on two gx2's in quad sli, but I was finally convinced to wait for the new gpu to come out (hopefully this summer?) so I am going to just get one card to hold me over until then. The 8800 that I would get is only a little cheaper than a 9800 gtx, so I decided to go with one of those because they overclock better, and in case the g200 (or whatever they will call it) line doesn't deliver, I could just get another gtx and sli them. (Maybe tri sli?).
Here is my parts list:

So there it is (unless I have forgotten anything) Again, I would love to hear anything you have to say. Is something I put up there not compatible with something else I put up there? Is there something I overlooked that could be upgraded further?
Also: I know that this is a hefty rig, and that it totes a hefty bill. I have thought about it, and this quality/price is what I have decided upon.
Thank you,
Duncan Harrison

Wow, That is going to be a pretty hefty rig, Some things have changed somewhat since you have been out of the loop, PC P&C still has nice PSU's, However the competition has become very competitive for the top dog spot and frankly I would not pay $479 for their 1000 watt unit when you can get just as good if not better quality for a couple of hundred less. Silverstone has some great Power supplies, Here is a review pitting Silverstone against PCP&C

There are other models on the market now that are very solid and are priced far less then the PC&P model, You might want to wander over to the PSU section of the forums and get some insight from some of the PSU Pro's.

Alright, thanks a bunch for the quick, kind, and nice reply. I guess I still have some more research in the psu department to do. Thanks for the link too to get me started

i would get this board so u could have DDR2 ram.
DDR2 800 with a CL of 3 or 4 is faster than DDR3
