John Carmack has been quoted as saying that Doom 3 will not run well on a Geforce4 MX and Unreal Tournament 2 has a predicted 26FPS on a GF4, so if you are a hardcore gamer and want these games you need a Ti4600 with 128MB RAM, or you need to wait until they bring out a GF4 Ultra which I bet they will call the Ti4800
