With radeon he'll get a HUGE performance drop in windows too in some games and not only in Dolphin.
My wife used to play Ragnarok Online with 2011 radeon card (don't remember exact model, we sold that laptop).
In same place GeForce 6600 + wine had full speed, radeon had 1-2fps. They still can't make good drivers.
With nVidia everything is fine. And not even close to 100% difference in performance between linux and windows. 2-4 fps at max and sometimes linux build is faster.
PCSX2 - GSDx software runs just fine, OGL plugins yeah, broken. And yeah it's much worse in terms of compatibility than Dolphin so i prefer to use real hardware.
A bit of offtopic - PC version of Jet Set Radio runs WAY faster and smoother in CrossOver in Kubuntu than in windows. Same with NiGHTS into Dreams... Oops...
