How about a mid 2012 MBA 1.8Ghz i5 with 4Gb of RAM? I'm running Yosemite now and it seems to handle it fine.
#1 You already have a SSD.
#2 That ain't no Core 2 Duo.
Mid-2012 and later Macs have the GPU horsepower to deal with Yosemite reasonably well. (Could still speed it up a bit by ticking the "Reduce transparency" box in the Accessibility settings.)
You're still short on RAM, but so long as you're not doing much more than word processing or web browsing -- and you don't habitually leave Chrome up all the time -- you may not notice because when you use virtual memory your SSD is taking up some of the burden and it doesn't slow down your Mac to the same extent that a hard drive does. Even so, play a couple of hours of shows from Hulu or do a bit of work in any of the core Creative Suite/Cloud apps and you'll see your Mac slow down conspicuously from lack of "real" memory.
