i just got jaguar and i'm very happy with it but when i have a lot of apps open and some times with out any open, the dock animations and some of the genie animations seem jurky and not smooth. i have a 400 mhz processor, 704 mb ram and a 16 mb vram video card. would i get a smoother look if i upgraded my video card? if so should i got straight to a 64 mb vram or will 32 mb vram do just fine?
