1st Gen Al iMac with Yosemite?

[Morod]

Hi all,
I really liked Snow Leopard. I didn't get Lion or Mountain Lion at all. But when Apple stopped supporting SL I got Mavericks. I'm currently on 10.9.5 and everything works fine. It's not only not as bad as I thought it would be, I like it!
I'm using a mid 2007 Al iMac, 24", 2.4 GHz Core 2 Duo, maxed out at 4 GB RAM, and an ATI Radeon HD 2600 Pro 256 MB graphics card.
Any ideas if Yosemite will be okay with this system? I know I can install Yosemite on it, but does it have enough "oomph" to run halfway decently? Again, Mavericks works fine on it.
Thanks for any advice on this, particularly anyone with the same or similar iMac who has been using Yosemite.

My $.02 is that SL works the best on that model. Given the headaches people have posted about bugs and issues, I'd be a little hesitant on upgrading to SL.

Apple's site shows that it will run 10.10

So its possible to install it.

I have Yosemite on that machine, but with 6GB of RAM. It is running fine. The only thing slow is hard drive related tasks, such as booting up, logging in after a log out, etc. Once it's up and running, it's quite good.

Thank you for the replies!
I'll probably upgrade to Yosemite after 10.10.3 is released.
