best motherboard for this configuration?

Is the price you listed for a pair of video cards, or for a single card, because that is damn expensive for a single card, and not enough for a pair of cards, ....which makes me suspect the former!

I any event, I'd look for a 975x SLI based board from Asus (P5N32SLI?), with the half/partial hopes that it might support a Conroe later...

and i am from belgium in europe so its more expensive here i think

from ur config, it seems to me that u might want to upgrade to dual gfx card later on...so i suggest u get an sli mobo...sry im not so sure abt sli mobo that supports intel chips...since im always using amd socket 939...and if u are going for dual core processor, y not get amd athlon X2?

i would also suggest that u get bigger ram. with such a high end processor and gfx card, 512 is just too little...in fact, it is way too little...it will only limit the performance of dual core processing...which actually defeats the purpose of u getting dual core processor...the least u should go for is 1 gig ram...(1 gig ram is the recommended system req from most high end games nowadays).

yeah what motherboard would be a good one for the socket 775(intel 940)?

do you know a good online shop for belgium or the uk?
i am ordering from www.codima.be

You need RAM. A BATTERING RAM.
