Graphics cards who's using what?

HI All
Been a while since I posted hope you've been keeping well.
Looking to upgrade to SW2008 but I'm being told that my 128MB NVIDIA
Quadro 980 XGL are not really up to the job. (Shame I've really liked
them they've been a great work horse to us over the last 3 years)
I know solidworks list recomended graphics cards but just wanted to
see who's running SW2008 sucessfully in the real world and what cards
they're using.
We've 12 seats on 2.8Ghz PC's, 2GB RAM used for plastic component/
sheetmetal design and max 5000 part assemblies and we do currently use
photoworks.
So any real world experience of suitable graphics cards for SW2008
greatly appreciated.
The hardwares do for an upgrade as well. Was thinking of going 64 bit
XP, our IT dept recently upgraded our MRP system and its now Web based
and really RAM hungry (using tab browsing helped a little, shame IT
didnt know about that little gem until we pointed it out to them), and
you guessed it we normally need to have both apps open. So I thought
64bit might enable us to crank up the RAM.
So any one with experience of 64 bit Xp and Solidworks, advice also
greatly appreciated.
regards
Ken
