Sometimes that crash is not always a crash. First time i loaded up GWX 3 it took a very long time to load it still takes a very long time to load but the first time i was about to hit that reset button during loading the red line you sit and stare at while waiting or is that just me

Stopped and the red light on my pc stopped for a good couple of minutes I thought yep shes crashed, wait i'll give it more time and went of to make a coffee came back and game was started. So prepare to sit it out, but then again my pc aint some superduper rig.
My cpu is same as yours except I have 2gigs ram and 7800gtx card. I think more ram would help and sometimes ive found changing graphic drivers - going back to a older driver works for certain games
