Latest NVIDIA en kernel update

[Manne Merak <mannemerak@xxxxxxxxx>]

I see there are some discussions going on the nvidia, KDE and arch 
forums about the performance of KDE 4.4 and latest nvidia driver, no 
results yet as I can see.
My current setup with 190.53 works fast and snappy (no special xorg 
param); but updating to anything later drops performance by a factor, so 
I resisted upgrading nvidia.  Now with the latest kernel update I cannot 
keep the 190.53 driver.
Anyone have a solution for performance tweaking the latest KDE and 
nvidia combo?  (I dont want to get too out of sync with the updates).
