minimum cpu requirements

[tbo]

What's a good minimum crap cpu to target? I'm making this game, so far it tests great on a few dual cores and a single core 3GHz. but its a little choppy on my old single core 2GHz / 1.25G ram/ radeon 9600 video. (haven't tried it on a mac yet :worried:).

Assuming i will some day present the game on some game portals, can i get some opinions on the older cpu threshold?

thanks.

Suppose it depends on your target audience. ^_^

Lots of people are getting around with netbooks etc, with a 1.6-1.9ghz single or dual-core atom? I would expect most casual games to be able to run on this fine, but if it is something more involved or really worth playing it could set a higher target like those desktop \ desktop-replacement laptop seeming figures.
