That kinda explains it, no offence but most people on free for all suck big time. I'll win 8 out of 10 games with a sniper on free for all. could probably win free for all with a pistol.
I find it funny that you bought a monster setup and are playing through Diablo 2 with it. When I first got my 465 and upgraded from a 4890 I was running through all my DOS games.
