Strongly NOT RECOMMENDED!!!
The 9550 series is a very much cut down version of the 9600 cards.
Contrary to the description on Amazon, it is actually NOT a quad pipeline card. It's a quad pipeline card with two of the pipelines dissabled!!!
It would work OK for MAME.... but if you run any other 3D or Direct-X software, then don't even think about wasting money on this. It's SLLLLLOOOOOWWWWW!!!
If you're only going to use it for MAME and for its TV out, then it might suit you, but why buy this when you can pick up a 256Mb 9600XT for about the same money.
