I got some amazing advice from the guys a few years ago when I built my new system,

currently running :

intel e7200 @ 3.4ghz.
4gb corsair ddr2
ati 4850 512mb
1tb samsung hd
corsair 550w psu
standard dvd drive

I'm looking to completely build a brand new system but reuse my hard- drive and dvd drive I want to get an entirely new parts for the rest.

Im looking to get an i7 based system so it'll last me a good few years, with a good graphics card.

Going to overclock the system as well,

currently thinking

core i7 950
nvidia 460/ 470 or equivilent radeon
6gb ram
possibly a small ssd just to install windows on.

So what im needing advice on is:

what mobo, I'd like it to support sli / xfire
what psu to get, pref modular as my current cpu isnt modular.
what brand of ram and at what speed?

good cooling for overclocking, water cooling is an option but not certain wither i'd want to try it.

Thanks in advanced
