Would Adding More RAM Lessen Texture Caching?

[Psycho Fox]

My PC runs all my GC games impeccably and I rarely have any issues. However, when I play Wii games there's often stuttering as the game is loading new textures into memory. I realise that this issue is lessened the more one plays a game but it's really tedious playing something like Mario Kart Wii which skips during every race for the first lap or so.

I've got 8 gig just now. Would upping it to 16 help or is the bottleneck on the emulator side?
