How many fps will I get in minecraft on multiplayer?

Well your specs definitely matter but fps is also based off of your internet and the server or host connection so my best suggestion would be to get on minecraft hit f3 and find out

Again as Nick said it does depend on internet, assuming you have decent enough internet you can probably max out e0 fps easily. I have a laptop which is probably ten times lower than yours and I get 5 to 10fps. Of course if you need to ( I don't see why you would need to though) you can mess with settings. But pc parts wise, 60fps plus is probably about right. Hope this helps.
