This is an update 2 my earlier post/question. I finally found the Ti4200 but it comes in 64MB & 128MB version. The price difference is 100 dollars so am wondering is it worth to pay the additional 100 dollars to get the 128MB version? Btw, am using an AMD XP1800 if you r wondering. So will there b a big difference in using the 64MB & the 128MB on my pc?
