61.77 Omega drivers work well on this. My buddy's PC has that card (I just recently canned my 5200 AGP), and he went through abut 8 different driver sets (53.03 on the install CD, iirc, and about half of the newer drivers on the Nvid site). Installing the 61.77s cured some really odd issues he had. I suggest those first, and if you're adventurous, install later drivers, and compare performance.
