So in most games i get a decent FPS, such as on GTA V my FPS rarely drops below 100.

When I have a high FPS, my GPU is running warmer than my GPU such as my CPU is at 40c, and my GPU on 55c.

However, when i go on something such as Garry's Mod on a server lots of stuff going on, my CPU works harder and runs hotter than my GPU by about 5 - 10c.

Final Question
Why is it that when my GPU runs warmer and works harder i get a better FPS?

But when my CPU works harder than my GPU i get a lower FPS?

I'm so confused, i can run GTA V on ultra with no lag but get a ton of lag from a game made in 2004!?

Different games stress different components for different reasons. What you are experiencing is perfectly normal.

If you were to load up a game from 1999, the original Everquest MMO, and joined a raid of 53 other people, or walked through a highly populated area, your FPS would get crushed no matter what the hardware is.

Some factors include whether or not the game is written to make use of multiple CPU cores. Another reason is the type of server the game uses. I don't know any good way to explain that one, but again, your experience is completely normal.

Some games are very CPU-intensive.

It's so hard to explain but so frustrating. On an empty server My GPU works harder and I get around 500 FPS

But when I join a server with 50 people, i drop down to about 20 - 40 FPS.

I've been thinking its a bottleneck from the CPU so I've overclocked it from 3.1GHz to 3.3GHz to avoid to much heat. Haven't seen a noticable improvement though.

On an empty server, your system only deals with you.
On a server with 50 other people, your system now has to process data on you AND 50 other people. And if that is causing you to slow down, then I suspect the software is extremely poorly optimised.

On the live E3 game broadcasts last week, during the GTA V portion, the host was having trouble finding a GTA V server that was not overloaded. And he switched servers for about 20 minutes of his hour before finding one that had a light load.

You pretty much answered your own question. When you are alone, you are bottlenecked by the GPU but on a multi-player setup, you end up bottlenecked by the CPU.

Numerical temperatures have nothing to do with it beyond the differences mirroring how the bottleneck shifts around - components that work harder get hotter.
