I too will be getting a geforce4 ti4200 soon. I was going to go for 128mb, but on the
new AnandTech Unreal tests they did, the geforce 4 ti4200 64mb got higher marks on every one. They stated:
"With a number of upcoming games based on the latest Unreal Engine, performance under this benchmark is extremely important. The numbers we've shown you today are more important than any Quake III score or any number of 3DMarks because they are produced from an engine that will be the backbone of many next-generation games to come;"
But previously on the
AnandTech GeForce 4 Ti 4200 Roundup, they had declared that "Based on [their] 64MB vs. 128MB discussions it would make sense for you to go with a 128MB card."
So I still cannot decide what I will be getting. I think I might be getting a 64mb, because of that Unreal test. AnandTech didn't make any comments on the 64mb doing better then the 128mb, which I wish they had. I still have at least a day until I can't wait anymore and I order something, so I'm still debating...
