The 9550 is a downclocked 9600 with 128 bit memory paths, 250Mhz core and
200Mhz(400) memory. Kind of like a Radeon 8500LE or 9100 with slower memory
and DX9 compliance.There's also an "SE" 64bit version in the works. In other
words, it's a complete POS designed to compete with the equally shitty but
DX9 compliant FX5200 series. There's absolutely no need for this bottom
feeder card. The base 9600 is a DX9 card, 128bit, and has 75Mhz faster core
speeds and memory speed is the same in the non-pro version.
