My understanding is Minecraft is heavly cpu dependant (due to being Java based), but if no one else comes by who has proper knowledge of the game you may do better to post on the Minecraft forums.
I somehow missed the part about GTX 770's running the game at 500 fps. A fewe things cross my mind in relation to that -
They don't use the same mods, and the rest of their system is configured differently ? You have V-sync enabled and they don't ? They are running at a lower resolution ?
Maybe you have more things running in the background, and have a stack of Tabs open in your browser while they have their machine focused on the game with very little running in the background, and no browser open ?
The 770 owners are having you on ? ....
Have you run montiors to verify the cpu, gpu and RAM use ?
I know a lot of people think using the Page File is redundant, but if you have the PF disabled try re-enabling it (Control Panel \ System \ Advanced System Settings \ Advanced - click Settings in the Performance tab. Go to Advanced \ Virtual Memory and set up a Paging file of about 4GB min and max (custom size).
