geforce2 Ti is the second-best geforce2 you can buy. first being the ultra. it has a 250mhz gpu for 31,000,000 triangles a second and 400mhz ddr memory for 6.4gb/second of bandwidth. with hardware transorm and lighting (T&L), it will run all but the newest games with ease... especially if overclocked.
the only drawback would be no infinitefx, which is what the geforce3 and 4 offer. but you also pay a bit more for those.
if you can get a geforce2 Ti for less than about $80 usd, then it's a deal. anything more, and you might as well get a geforce3 ti200 for $110 or so.
