video card upgrade question

right now i have a radeon 64 VIVO in my system, i'm on a tight budget to upgrade since im a dam college student lol, well anyways i was looking into buying a geforce 3 by visiontek for $100 i looked it up at pricewatch.com and enpc.com is selling one for that much and i know its just one video card generation newer than my current card but i cant afford a geforce 4 but do you guys think it would be worth it to spend 100 dollars for a geforce 3 so i get some extra boost in my games and probably next summer upgrade to the top of the line video card? i just wanted some opinions on this matter if it helps i play games from anywhere like jedi knight 2 to neverwinter nights and also looking forward to the star wars online game and im stick of ATI implemented new official drivers with this catalyst that doesnt work yet in 1/2 the games that have came out this summer and makes my system lock up thanks
