Cons that I'm aware of:
Somewhat "custom" simms
May not be able to use Blizkick
Pros:
GVP product quality was on par with anything
else out there. The overall build and "finish"
quality of the old GVP card I had was actually
*slightly better* than my DCE 1260 card, and
that says quite a lot IMO (surprised me anyhow).
-edit-
GVP made some solid boards, if the price is
reasonable I say "go for it"...
