I came across a review for CoD and along side the system specs was neat little box in which you typed in your current PC specs and it gave a rating out of 10 for performance......mine came out at 4...........
So I priced up an expensive but decent spec upgrade, typed it in and it came out at 7----hell! Think I will wait untill prices have fallen and stick with 4.101 as I am not sure I could cope with an underperforming rig - it would drive me nuts!
