Yosemite on 2010 iMac

[malcolmffc]

I have a 20.5" iMac bought in Dec 2010 (core i3 3.2 GHz, 12 Gb RAM) running Mavericks. I'm keen to upgrade to Yosemite but am nervous that the new OS and graphics features will make my machine crawl and it'll be an OS 7 on iPhone 4 type situation.

So, has anyone else done this? How well does it run? Any info appreciated.

I have a 2011 iMac and the only thing that affected me is the fact it doesn't look amazing on a non-retina display. Its not bad looking and its not great either, but Apple is clearly targeting retina displays with Yosemite.

However, it performs as intended, so I'm happy with that. I can't be bothered with the hassle of downgrading, so I'll stay on Yosemite.
