upgrading soon some suggestions ?

[mikekim]

So now looking at going 12 gig of ram, but looking at the ram, there is quite a few different brands and lots of different prices, what should i be looking at, and why the one your suggestion ?

Doesnt really matter as when you move up to 12Gb+ you are looking at running the ram at 1333mhz (only a handful of boards/ram support 1600mhz at this level)

I heard i7 motherboards is the way to go ? Will that be the same deal come June ?

looks like it - you will probably get a good deal on 1366 systems, as most will be looking at 1156 (sandy bridge)

Graphics card, I run dual screen plugged into the 1 card, want to keep it the same way again probably... was 1536M GTX580 Inno3 Asus a good card to use ?

any GTX580 will work - don't bother with overclocked versions, you can overclock yourself with MSI afterburner.
GTX 570's are worth looking at as they are getting very good reviews

Currently I use windows 7 but home version, when I upgrade going for ultimate and 64 bit.

windows 7 Home supports up to 16Gb ram - ultimate tbh is a waste of money

What are peoples suggestions to build a very good box too support 5 clients in cities + BGS and on graphics on High on all clients at least if possible all running off the 1 machine.

simple really
i7 - pick your flavour
GTX 570+
12Gb Ram
SSD (at minimum for wow data)
