Yeah, I said handle for lack of a better word. But if you are making a mod, It wouldn't be smart to make 10k+ poly models as alot of people would have a hard time playing the game. 2048x2048 textures look really great but only on screens that are larger than 1600x1200 pixels or else you won't notice that much of a difference (Just look at FakeFactory's Cinematic Mod, it has 1024x1024 textures for normal citizens and 2048x2048 textures for people such as Alex, but I can't see that much of a difference as my screen is only 1280x1024 large.)
@Movento: You could put quite some detail into folds, but then again, these days we have bump maps so I don't think it would help that much, don't know how bump map technology works. And you could also put alot of polies in hair/face. I don't think it is that hard to make a 3,500 poly model for DBZ. Vegeta from the Buu saga might be a bit hard(As he has one big bland suit, there is not much detail in it.), but for other characters it should be alot easier.
