I'm running the same kind of card on my station Perks and I've yet to experience any problems with it. It may not be the latest and greatest, but it is a good card. That's not to say that it won't take a dive sooner or later, but then you'd be experiencing gliches in most of your applications that use the card and not just confined to Poser. Check your color settings to see if it's high enough (I run true color).
