That card looks fine. My only concern was that theres no reviews for it on newegg but the Jaton 32MB model with the identical chipset, has got good reviews - all from people with older systems, which is encouraging.
Also, as you pointed out, the motherboard manufacturers appear to have been in cahoots with nVidia when it came to the video testing, so I guess nVidia chipset would probably be the best one to go for.
