That's more of an issue, I found when I was using the G550 PCI alongside even the intel GMA, it would not recognize unless I disabled the GMA, whereas in XP it worked fine.
I don't think you can run the 'starter' edition type of windows7 desktop alongside anything with higher driver support. So I can't advise on that other than it didn't work for me. It might work for you though, and if you've already got the gear, no harm in trying, but if you're scouting the egg for gear, I can't be sure about that to the point of advising.
