WoOT - Looks like Nvidia has fixed the crashing issue!
As some may know, I have had a crash issue (with Sins) using newer Nvidia drivers after 97.46 (Vista).
I know some of you have had a: hard crash/freezing/minidump/driver (failure/recover) ... I've also had these issues since beta 2 - ALL OF THEM!
Well, not any more 
I installed this new 174.74 driver (beta) from Nvidia last night and have been playing Sins since - w/ no issues.
I've listed the links for all op system users (Vista users may want to get SP1 before using this driver)
Supports GeForce 6, 7, 8, and 9 series GPU's:
XP link = http://www.nvidia.com/object/winxp_174.74.html
XP (64bit) link = http://www.nvidia.com/object/winxp64_174.74.html
Vista link = www.nvidia.com/object/winvista_x86_174.74.html
Vista (64bit) link = http://www.nvidia.com/object/winvista_x64_174.74.html
It must've been some big flaw w/ past driver(s) as you can see ALL series are supported on ALL platforms by this driver - hmmmmmm.
Thanks Stardock/Ironclad for keeping on Nvidia about this issue - it's been a LONG ROAD !!
PoorManDSO out!!!
