also, most games on PC only use either 2 or 4 gigs of ram. For something that's made with gaming as it's main purpose, 8 gig would almost be too much. 4GB for games and 1-2 for system-level stuff would be more then enough.
It was working fine yesterday and I upgraded on day of release but today I haven't been able to play more then 15 minutes of Diablo 3 before the game crashes. But I played many hours yesterday without problems. Also, no other problems or issues. so.. No? I have no clue.
