the velocity is very fast, faster than v3 2k. You can run 1600x1200@32bits with 8mb so no problem. ALso the 2d is very good. the only thing i can think is that 3dfx is out of business. the tnt vanta is probably slower than a regular tnt1 and probably has crappier 2d quality. but it is well supported. personally if i were you i'd try and hunt down a 32mb ati xpert2000, or a 16mb xpert128 (aka rage fury 16mb) for around $40. They are both faster than the vanta (especially the 16mb since it uses a rage128gl chip and the xpert uses a rage128vr with 64bit buss), have decent driver, better dvd, etc. Also better 2d than the 3dfx or the vanta. with just a 400mhz celeron, you really wouldn't be pushing a velocity 100 to the limit, and a rage128 card would fit very nicely for a CPU of that class
