Could you give a lowdown on the specs on your machine? It would help paint a better picture on the hardware the OS is running on.

Before resetting I'd run Activity Monitor and look at the CPU, Memory, Energy, Disk and Network options to see what applications or processes are consuming the most resources.

That may help pinpoint what app(s), or process(s) are contributing to the lag. System Diagnostics can also be launched from Activity Monitor. The diagnostics may help Apple Support catch something if there is a system problem. If it turns out there is a hardware problem or lower level firmware issue, then a full back and reset may not help since the problem could reappear after restoring data.

Also, using the much referenced but valid option - if you are under Apple Care - then call in to Apple Support, or setup an appointment at an Apple Store if that is an option for you.

My MacBook Pro is far older and less powerful, and runs Yosemite pretty smoothly.

As others mentioned, run Activity Monitor and check out what is eating CPU usage and memory/Ram.

Also, if you didn't run Disk Utility before upgrading to Yosemite, run it now. Verify your Disc and Disc Permissions to check for any errors... and if any are found, click Repair Disc and/or Disc Permissions.
