As with all drivers I recommend running a clean install, but its now built into Forceware drivers, just run a Custom setup (not express) and you are given a check box under all the drivers for a "Clean Installation." Check this.
I am linking the official drivers and a good modded INF driver I have tested this morning.

You may get a missing file error if using the official nVidia one, I just copy and paste all the new files into a working driver set I have had before... for some stupid International English reason... Please refrain from running around screaming in my thread like you just had a shaving accident on your bikini line. Let us not forget we are PC users, save that kind of thing for the console forums

I have a quick fix for this, see below.
Example:) 267.31 recognizes my card, for everybody else its usually 267.24! I copied all the contents of 267.84 into the 267.31 folders overriding everything. Problem gets solved. Its just a small unincluded file not pertaining to visual drivers that is left out of some nVidia released ones. It happens. I do that whole copy paste shenanigan because I am too arsed lazy to actually found out what tiny file is missing. Instead I squash the whole archive Power Kick style, f*ck yeah! Okay enough of my silly-ness.
Check Guru3d or Laptopvideo2go.com, they are pretty on top of doing all that for you if you want to wait and don't like to manhandle your drivers (or lady handle... I think Goddess84 plays Crysis). I keep forgetting chicks play games, so don't mind me. ANYWAYS, onto numbers:
The performance is increased by about 10% in Crysis 2 over 267.59 betas (which were already pretty damn high 120fps+)
2x GTX 580s
Average FPS ~ probably just 130 fps, dips to about 100 when there is really hectic on screen nuts explosions, helicopters, and buildings falling on your head simultaneously, but I usually am sitting at 140~160 fps running around.
Cool thing to add, 90% of the flickering light reflections/refractions are gone

P.S. In the time I rambled and said stupid sh*t, I could have just written a posh little modded INF install guide like the little "Posh elitist PC turd" that I am =) In that tradition I am leaving you little buggers on your own, after all thats why you have a PC so you can do things for yourself, and not have your little muggen hands walked through everything.
