the mx400 is a geforce 2
it's the best of the geforce2 mx series
it's based on the geforce2 gts chipset
basically, they just run the ram and gpu at a lower clockspeed
if you buy a fan for it you can o/c it from here to kingdom come
you could easily get geforce 2 ti speeds
i bought mine for $130 on sale, potentially minus $40 from a mail in rebate i have yet to recieve
future shop sells my video card for $150
visiontek xtasy 5564 geforce 2 mx 400 64meg
www.nvidia.com has all the info you need
gf2mx400 is a good buy for current pc users
for future users ... i'd say wait until the gf4 is obsolete, and buy a gf3
staying two generations behind generally keeps you up-to-date
pretty funny
