I get a different problem with my new GT240 - the system often freezes, sometimes and locks up or hangs entirely. Even Task Manager may not start so I can't terminate the process, and this is with the newest drivers as well as 260.99. Turning off hardware acceleration fixes it, and the performance penalty in committing assets isn't too bad; it takes about the same time to commit an asset as with my old 8400GS. Still, though, Alberte's right and it would be nice to be on the accelerated side even if it doesn't affect in-game performance.
