spec check please???

[Flare]

It would be greatly appreciated if a few people could leave me some comments/suggestions on what the spec PC that i might buy.

It will most like be the following:

- Sapphire ATI Radeon HD 4870 1024MB
- Intel Core 2 Quad Pro Q6600 "Energy Efficient SLACR 95W Edition" 2.40GHz (1066FSB)
- Asus P5Q Pro intel P45 (OR the Biostar Tpower P45)
- Corsair 4GB DDR2 XMS2 PC2-6400C5 TwinX 2x2GB (MAYBE Corsair 4GB DDR2 XMS2 Dominator PC2-8500C5 TwinX (2x2GB) Supplied with Airflow Fan)
- Corsair TX 650W ATX2.2 SLi Compliant PSU

I would greatly appreciate it if someone could tell me which mobo is better and if its worth spending double the price for the dominator RAM, bearing in mind that i would like to save money if it wont make much difference.
Bearing in mind that i will be overclocking and adding a 2nd 4870.

Thanks in advance,

so what about the mobo and the the ram?
both motherboards are pretty much the same price but the dominator RAM is £84 where as the other is £42...

yeah i have AS5 in my basket.
Im now just tryign to deicde between the 2 motherboards i've mentioned and the RAM i mentioned.
I have a rough idea of what CPU cooler i want

Btw, thanks for all the help people

just had a look at the biostar i would avoid that as it has an inbuilt fan on the NB which would block an aftermarket CPU cooler air flow

it isn't inbuilt, it comes seperate. . .
"Biostar's TPower I45 comes with this screw-on MOSFET heatpipe heatsink for an extra cooling boost."

So if i'm aiming for over 3.5GHz go with the dominator, if not the lower ram will be fine?
I think i will just leave the dominator ram then and maybe upgrade in the future if i want to.
