Anyone have problems with these components?

Time to build a new computer. Generally I use my comp at home for gaming and general web search. My game of choice right now is WOW. Should I have any concers with the components I'm considering for this build? I've been doing my best to read reviews and get quality parts. I dont do any real overclocking. Here is the list:

Evga nforce 680i Sli MB
Q6600 2.4Ghz processor
OCZ GameXStream 700w Power Supply
PNY XLR8 Geforce 8800GT 512MB DDR3 Video Card
Zerotherm Butterfly BTF90 CPU cooler
NZXT Tempest Case
4G Corsair Duel Channel TWINX PC6400 800mhz Memory
Seagate Barracuda 7200.10 320GB Hard Drive - 7200, 16MB, SATA-300

Any thoughts would be much appreciated. Was also considering going with ASUS MB in place of the 680i.

Scrap the SLI motherboard unless your going SLI now, or in the next couple weeks. Trust me i made the same mistake. I paid 240 for my SLI motherboard, thinking i might SLI down the road. But it's more likely i'll replace the existing card with a much better one. So i'd recommend a nice p45 mobo for about 150. Or better yet a p35 for even cheaper. Also, the nvidia chipset is pretty notorious for causing problems. Well at least in my experiences.

For example : My dad bought a Dell XPS 600, it's an Nvidia chipset 680i. Ever since he bought it, it would occasionally get a BSOD. With my mobo, XFX 680i, which is identical in every way to the EVGA 680i, it had various issues with overclocking. Although i did get lucky at stock. I also have finally found a stable OC, which took months. BUT my dad has built computers in the past. ALL intel chipsets. I don't remember any of them ever getting a BSOD...ever. We just retired an 8yr old motherboard by ASUS, only reason was the input on the mobo stopped working. Or so we figure.

That processor is great, but not spectacular until it's overclocked. If you don't plan to overclock, the wolfdale line of processors will perform better. If you really want a quad then keep it, but don't expect a ton of performance unless you overclock it to at least 3.0ghz. Which BTW is very easy to do, i'd be glad to help if you decide to.

I'd recommend a Corsair, PC Power & Cooling or similar PSU. OCZ isn't the best company for PSUs, and that is the one component you don't ever want to go cheap on.

With the money you saved on the mobo, i'd go with either a 4870, or gtx 260 preferably the 216 core version.

Xigmatec cooler, with back plate. Can't get any better for air cooling. Although if you don't plan to OC at all the stock cooler will suffice.

That case looks to be pretty good, but i'd recommend the antec 900 or 1200, you may like one of those better.

No complaints on the ram.

Not sure on the HD, but i think you can get a 640gb from western digital for the same price.

GL with your build.

I was considering the ASUS P5Q Deluxe, or P5Q Pro w/ the E8400. The reviews show ASUS to be a quality board, better energy consumption, better on board cooling system, quality capaciters. I leaned towards the 680i w/ 6600 because of it coming in a bundle pack for less money ( $309 ). Anyone else have problems with this ASUS board? It seems that regardless what you choose, there is about a 10% group that doesnt care for the MB, cant get bois to work, or has some other complaint. What do you think of these ASUS boards?
