I have the NVidia GeForce2MX400 card. Dell computer, Intel 1.9, 512 mem, XP. I also have a 179 dollar piece of software reclining in my computer that is pretty much useless to me. :( I am rather new to Poser (only bought Poser 4 in June), and love it so much that I was really excited about getting the upgrade. I should have saved my money. Either the software is buggy as heck, or my computer just plain hates it. I have gone back to Poser 4. Was tired of fighting with 5. ::sigh::
