i think that i am going to just go buy a 4400 in a couple weeks unless 2 things happen: 1) there is an indication that ATi/Matrox will be releasing something worthwhile in the very near future, or 2), there is an indication that the 128 MB ti4200 is going to be a killer overclocker. i already have a ti200 oc'ed to 250/530, so i don't think that i will be able to justify getting another 64 MB card that doesn't outperform my current card by that high of a margin. also, since a friend of mine has already agreed to buy my ti200 (for $90 or so, which is only $10 less than i paid for it new) when i upgrade, the ti4400 wouldn't be THAT much more expensive than the 4200.
