Well, my computer which is now a little over a year old, will run Diablo 3 comfortably. I did have to turn down the resolution a bit, but otherwise it ran as smooth as glass. I was initially worried that my notebook wouldn't run it, but after holding my breath and downloading the Beta during the open weekend, I let out a small sigh of relief as everything worked well. Not sure I want to post my stats here, though...wouldn't want everyone laughing at me.

But here goes:
HP Pavillion dv6-3122US
4 gb ram
500 gb hard drive
AMD dual-core processor @ 2.80 ghz
AMD M880G with ATI Mobility Radeon HD 4250 graphics card
Yes, I can run Skyrim as well, on medium settings...so despite the computer being "old", it seems to do well. I know my luck won't hold out forever, but at least I can enjoy the Diablo 3 experience...
EDIT: Ah, sorry folks. My processor speed is 2.40...not 2.80.
