I have
ASRock x79 extreme 9
I7 3820 3.8gHz
EVGA GTX 670
16Gb corsair RAM
All drivers updated

Perhaps I'm expecting too much from the graphic cards, but there seems to be an FPS drop in most games when set into max settings. I have vSync off and AA set off in most games, but even then there's a rapid constant FPS drops

For example, TERA, I don't expect there to be an issue but at max settings, it runs at 60-70 FPS and then suddenly drops to at lowest 20 every minute for a second, at worst even freezing for a sec.

Temp shows to be 35 degrees at idle and rising up to 60

Turn adaptive Vsync on so you don't get screen tearing. Also yeah A LOT of people have that problem with tera. What other games are you experiencing problems.

With tera it appears to either be horridly coded or UI issue. (for some people when they turn off the UI they get +20-30fps)

Sadly that was the only reason I quit playing it. I loved the combat.

In games like League (in which I didn't expect there to be any problem) it happens less frequently as other games, but I would be at 60 then drop down to 20-30 once a while, and with vSync on it goes 200 and continues to drop to 70 and up to 200 every second (the constant drop however makes it look VERY fidgety as if I were at 10 FPS

Vsync should keep it at 60 (or whatever your monitors refresh rate is) Have you tried forcing vsync in your drivers control panel?

Does this also happen in say furmark? (run furmark for atleast 10 minutes to rule out any overheating that might be happening)

Using latest driver version?

I'm often told Turning vSync off will improve performance, is that not right? I'm not particularly familiar with what it exactly does lol

I guess my computer is running fine, I'm just expecting too much out of it?

Turn it on! Let me explain.
Your monitor can only refresh its image so many times a second (usually 60 times) so any more frames than this will cause no differences to the image quality (as your monitors already working its hardest) but your hardware will still render the frames putting more strain on your hardware that their needs to be. With Vsync on it limits the hardware to produce slightly over 60fps making the components less hot. However this is effectively nerfing your hardware. If you have constant frame drops with vsync on its better its turned off as the components will be working at their max capacity already otherwise it should be left on.

So, I've been playing with the VSync on, and I'm not seeing that much of an improvement.

On the other hand, for League of Legends, there's a huge performance difference with VSync on vs off.

When it's off, it usually stays 200+FPS consistently often dropping down once a while now, but when it's on it goes to 60 and drops to 20 every second or so like I said previously, and it becomes unbearable to play because it really feels like it's very choppy.
