I have the latest nVidia drivers (275.33) on my Revo R3610 and I have no issues. I can't tell the difference between the older driver(s) and the new ones. I updated them because I can't help myself. Newer must be better - right? Fortunately the update did no harm (and maybe improved something I not yet aware of).
However, My advise to anyone who asks is "if the drivers you have now are working fine, leave them alone".
For me the road to 23.976 perfection, was switching to JRiver Media Center.
