I have a 2010 MacBook Pro with a 2.53 GHz Intel Core i5 processor and a 4 GB 1067 MHz DDR3 memory? Is it recommended to upgrade to Yosemite?

I've seen a lot of people reporting problems with older MacBooks once they're upgraded to Yosemite. Wanted to check if I am making a mistake by upgrading. Currently, I am running Mountain Lion and things are OK, but comparatively slower than when I first got the machine in mid-2010.
One option is to create a new partition (~30- 50 GB), install the new OS, and ‘test drive’ it. If you like/don’t like it it, you can then remove the partition. Do a backup before you do anything. By doing this, if you don’t like it you won’t have to go though the revert process.
