I honestly don't know what I'd do if I were going to build a new computer without recycling any parts in the next couple of months...... NVIDIA has new stuff coming out.... Intel has new stuff coming out.... Both Intel and NVIDIA have some very good stuff out already. Tough choices right now..... I'll post what I have running at the end of this post to give you an idea of the hardware that I like (other than the 680i motherboard).
Go with a dual core instead of a quad core (I have quads mainly because of World Community Grid)? I've seen some test results on the new dual cores (E8*** series) that looked
very promising. If quad core, QX6850, QX6800 (both can be found cheaper than the QX9650), QX9650 or wait on the Q9450???
Buy parts that are compatible with DDR2 (DDR2 is a
lot cheaper than DDR3) or buy parts that are compatible with DDR3 because it's the future?
Video cards...... Whew! Tough choices here too. The 8800GTX is very good. The 8800 Ultra is supposed to be a little faster. There's the 9800GX2 coming soon and the 9800GTX a little later..... Buy what's available now or wait???
I'm glad I'm not trying to decide on what to buy at this moment.......... That said, I'd probably buy an Intel DX38BT. The draw back to that board is that it requires DDR3.

Concerning the PC Power & Cooling power supplies..... The Silencer series is not noisy. Some of the Turbo-Cool series are noisy.
I built a new computer for my son back in the fall. The parts I used are as follows:
Cooler Master 690 case
Intel DG965WH motherboard
Q6700 CPU
Thermalright Ultra 120 Extreme CPU cooler
8800 GTS 640MB video card
X-Fi XtremeGamer Fatal1ty sound card
3GB (2X1GB + 2 X 512MB) of Buffalo Firestix DDR2 800 RAM
320 GB Seagate Barracuda 7200.10 (perpendicular recording tech) hard drive
PC P&C Silencer 610 power supply
Vista Ultimate 32 bit
I switched out the rear 120mm fan for a medium speed 120mm Yates Loon. Changed the 120mm fan in the side panel to a low speed 140mm Yates Loons. Added a 140mm low speed Yates Loon in the top and switched out the front LED fan for a non-LED low speed Yates Loon (son didn't want the light from the fan to bother him at night). That combination is cool and quiet.
The computers that I have are as follows:
Note 1: I'm running World Community Grid on all of my computers < main reason for quad cores.
Note 2: None of the following are what I'd call quiet due to the extra fans that I've added and the CPU's running at 100% 24/7.
