I'm thinking about getting a g4 ti4600. I am running a athlon 1.2gig @266 with 512 of pc2100 ddr. I currently have a g2 ultra 64mb card in there now. Should i get it? Will there be much of a bottleneck with my system? is it worth it to get it now or should i wait until the 8x cards are released? Any suggestions would be great. Thanks
