I seem to remember, a long time ago, it being said that MoH doesn't have the files needed to support gf4 so by upgrading to it you won't really get faster speeds (I have a gf3 64mb, 1.67Mhz Athlon XP and 512 DDR ram and my game flies over 90fps).

There is a way to sort this out but I cannot for the life of me remember how or what it is.

But, certainly, upgrading RAM and your CPU will always speed your game up, as already suggested by others here.

It's just that a gf4 on its own will not speed up MOH at all because the game engine code doesn't take advantage of the new technology (GF4 came out after MoH did, effectively).
