First of all, I'd like to mention the 190.38 has horrible performance for some setups in Crysis, it has to be a bug because I've seen reports up to 50% FPS drop. The NVIDIA drivers have been very bad lately, the last good driver IMO was 182.50 WHQL, I personally prefer 182.47 but they are quite similiar.
That being said here's my result but at 1680x1050 res because I'm using a CRT and the 1440x900 res isn't selectable and the display driver I'm using doesn't allow me to add custom resolutions.
C2D E8400 @ 500x8, 4.0GHz

So either your systems aren't configured properly or you're suffering a lot of performance due to a bugged nvidia driver. I beat all those results and at a higher res, I know my CPU is clocked at 4.0GHz and also a dual core but you already said CPU performance won't matter much for this game anyway. ;)
