Got a new computer now, old one decided to give up...

CPU: Intel Core 2 Quad Q6600 2.4Ghz
Mobo: Asus Maximus Formula
Mem: 8GB OCZ OCZ2N800SR4GK
Video: Asus Geforce 8800GTS 512MB
HDD: 150GB Raptor and a 500GB HD501LJ Samsung drive
Sound: Auzentech X-Meridian

Graphics card drivers this time around are 169.21 for XP x64 and 169.25 for Vista x64
Intel Chipset drivers v8.3.1.1009
The Creative X-fi was swapped out due to being a crap soundcard with crap drivers In it's place I'm using a Auzentech X-Meridian with drivers dated 9/3/2007

Resolution this time is 1600x1200, and all settings are on high


Windows XP x64 64bit:
Crysis Bin64 executable;
Average FPS: 32.82
Min FPS: 12.66
Max FPS: 38.55

Crysis Bin32 executable;
Average FPS: 32.86
Min FPS: 11.92
Max FPS: 38.12


Windows Vista 64bit:
Crysis Bin64 executable;
Average FPS: 28.31
Min FPS: 13.6
Max FPS: 31.41

Crysis Bin32 executable;
Average FPS: 28.42
Min FPS: 11.93
Max FPS: 31.10

This time around there is no difference at all to running the Crysis 32 or 64bit EXE in both Vista and XP...
However, Windows XP x64 is still 16% faster than Vista x64.
That's all for now
Take note that all hardware and software is different from the test above by me so they are not at all comparable... What we can conclude tho is that neither Creative nor nVidia can write proper drivers, Creative manages the feat to make their 64bit driver incompatible with more than 2GB RAM, and in Nvidias case their previous range of card manages a staggering 63% performance difference in XP vs Vista!
