I'm finally ready to put together a new build, I really wanted to base it off an E8400 processor but I have had a terrible time finding one at a reasonable price. I'm still looking if anyone happens to know where to find one. I want it to be a gaming rig but I'm trying to be a little conservative with my spending. "Bang for the bunk" I guess would be the term. I would like to o/c it to around 4.0ghz

Ok, so what I have right now is:
Case: Antec 900 case
Power Supply: a cooler master extreme power 500w power supply that I'm hoping will suffice
Sound Card: creative x-fi
Cooler: Tuniq tower 120

What I want:
Processor: E8400 (anyone knows where I can find one please comment)
Mobo: ABIT IP35-E LGA 775 Intel P35 ATX Intel Motherboard $90
Ram: CORSAIR XMS2 DHX 4GB(2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) $100 after rebate
Vid Card: EVGA 512-P3-N841-AR GeForce 8800GTS (G92) 512MB 256-bit GDDR3 $290
HD: Western Digital Raptor WD1500ADFD 150GB 10,000 RPM 16MB $170

Will that power supply be sufficient?
If you have any suggestions on where +/- $50 would make a difference please post that as well.

Thanks a lot for any suggestion and/or coments.

Tigerdirect is one of the few places that has it in stock for like $229, I think. That's about the cheapest you'll find it atm. (Last week it could be bought for $184 from NCIXUS.com) You may just want to keep an eye on the prices.

Power Supply: That PSU may work, but it's on Tier 4 or 5, meaning that it's not so good... Check out the 500W OCZ StealthXtreme. http://www.newegg.com/Product/Prod [...] 500W%2bOCZ
Much better than the Coolermaster and the price is very good.

Proc is fine.
Mobo is fine.
RAM is fine.
Vid Card is fine. (You may be able to find a better deal if you look around a bit -- it may not be EVGA though)
HD -- I'd go with a 500GB Seagate Barracuda 7200.11. It's got a 32MB cache, larger capacity, and just about as fast as that raptor. Much better "bang for your buck".

As regeist554 mentioned, the harddrive choice might not be worth it. You can currently get a Western Digital Caviar SE16 WD7500AAKS for under 160 dollars. This also competes very nicely with the raptor in most benchmarks. Keep in mind that the raptor is VERY loud and also can get quite warm. It's up to you. Just my 2 cents.

Another option for the PSU;
