Currently have a GeForce 3 TI200 64MB. Looking at an ATI 9200 for around $100.00 or the 9600 for $170.00(Both with 128 MB). What should I do, keep the card I have, or go with the 9200 or 9600. Is the 9600 worth the extra money? Or should I look at the GeForce FX line? Would be paired with a P4 2.0 ghz with 512 MB DDR Ram.
