Well yes and no:
Graphics acceleration in general is for the monitor you are looking at, in your case a client computer which has its own graphics card. So that one should be accelerated

Through its own OS features and its own graphics driver. See the point?
But graphics rendering can be a bit quicker on the RPi (serverside) and depending on your application can make a bit of difference even if connected through a remote computer. Don't expect X (and therefor your GUI interface) to be rendered quicker though. That simply sends graphics rendering commands to your client. And is rendered by the client. But you can expect a little gain in graphics rendering, because it takes less time to render on the Pi and send it over the line.
