Myself I am going to up from 4 to 8 GB and run Ubuntu 64-bit and XP32 in VMWare.
Sure 64-bit Vista is great, mind bogling, the computer never slows down! Running Unrar on 100 GB of downloaded torrents, downloading a torrent at 700 KB/s and working just normal with IE, Photoshop etc at the same time. Its truly a workstation.
4 cores sure help a lot. But Vista has not been so stable for me. And I have had quite a lot of problems. Plug in your PSP, need drivers (what driver? :crazy: )
Plug in 320 GB IDE hard drive, can not install, need drivers ( :-? ), goes to Seagates homepage "your hard drive does not need drivers" WTF :madashell:
I could make a long list, but the truth is out there anyway, (on the net :rtfm: ).
If Vista feels this fast on quad core + 4 GB, I wonder if the computer is going to take off from my table running Ubuntu with 8GB :-D (already running Ubuntu on my P4 server and I am impressed, coming from BSD background before).
