I recently purchased a Gateway - FX Edition Laptop with Intel® Centrino® 2 Processor Technology(its a gaming laptop) and was wondering if Ubuntu would run more effeciently than the Vista 64 bit??

i not too tech savvy so straightforward answers would be most helpful. I have a friend who runs Ubuntu but I dont know how it would hold up with a gaming laptop. Since its new id prefer not to install an operating system that would downgrade what I already have (vista 64 bit with sp1 preloaded). Anyone who responds I would much appreciate.
I'm not sure if it matters but heres the specs for my laptop---
