Just talked to two people in the office about Mass Effect PC and they are really pissed off.
One has a Quad core, dual 8800GT,4 gb RAM and he experienced an unacceptable level of crashes - around 20 from his playthrough.
The other one had a lower spec PC and already had 3 crashes in his first hour.
Coincidence of bad discs? Dont know but its really funny how people can argue the PC version is far superior to 360.
