Two monitors - that makes more sense then.Personally I would reduce the RAM to 4GB and with the savings go for two 8800GT cards. Your gaming experience will be a lot better, noisier but better. Dont get me wrong, 8600GT cards are good for games, but you cant SLi them if using Multi Monitors so having two wont be any faster, just better quality on two monitors (and not all games support multi mon setups so they would only work on one screen). Saying that, a £2k gaming rig cant play Crysis on max resolutions either so dont be disheartened!
In 6 months when DDR3 is flooding the market, buy the other 4Gb for £40!
I have two monitors on mine and two graphics cards - initially I tried one card but the resolution dropped to much. As for setting it up, really easy. In my case I use the nvid control panel. So long as you can tick a box you wont have a prob, but be patient as it may need a bit of tweaking to get it just how you like it. There are third party apps which are really good too, but i dont think you need them.
Vista Home Premium 64 bit - you're a braver man than me! There are bound to be software issues with such a new motherboard, DDR3 and Vista. I wouldnt want to make such a machine. I'm an XP Pro follower and 32 bit until it sorts itself out. To many bad stories about Vista. Apparently Service Pack 1 is due out or is out and if like XP, that made a big difference.
I'd say the main concern is 64 bit since most apps are 32 bit and that means RAM will max out at 2Gb because of the emulation mode Vista will adopt. There is also better driver support for 32 bit software.
That machine is 64 bit ready, you could have Vista 32 bit and go to 64 bit when its more stable, especially if using for work?
I'm trialing One Care its really very good now; first release wasnt much cop but the new one really is - with XP - it must have better Vista Compatability too being that its from its own stable! I've tried so many makes now and this thing keeps it simple and is less invasive than any others, and believe me i've tried a lot! You can always trial it too.
It doesnt have all the flashy bits and I read an article saying that Microsoft have to test the patches far more than other companys in case they are sued! so less likely to cock machine up.
