Hi All

I've recently purchased P7 and I'm currently waiting for Adobe CS3 Production and I'm looking for advice on upgrading my system.

This is my current PC setup
Pentium 4 -  3.00 Ghz
1Gb RAM
NVIDIA GEFORCE 6200
XP

All the revewies I read in magazines concentrate on gamers but nothing for Poser users so I'm clueless :-(
I think I might aswell upgrade to Vista and Core Duo (NO CONFLICT PROBLEMS I HOPE)
These are some components I've been looking at...
Intel Core 2 Duo E6600
Abit AB9 Quad GT (Socket 775) PCI-Express DDR2 Motherboard
Corsair TwinX 2GB XMS2 Dominator  DDR2 PC6400
GIGABYTE GV-RX195P 256-RH  Graphics card

That little bundle amounts to £523 without Vista so that my max budget.
Also What version of Vista? Premium, Ultimate or will Home Basic do the job?
Thanks
