I think the need to upgrade was one of the things that turned a lot of people away from PC's and onto consoles. Consoles stay the same for 10 years + but in that time PC's have changed hugely.
Oh I don't know, that means PC's are usually more up-to-date hardware wise, and gives me something to do once a year. :smilie:
I5-2500K (running at 3.8)
16gb Ram
GTX 570
The yearly update will be around October so above spec will change by the time E: D comes out.
