Is the GTX 760 good for Minecraft and Battlefield 4?

I currently have the Nvidia GeForce GTX 650 and it doesn't really run BF4 that well, playable, but not how I'd want it to be. So I'm thinking of getting a GTX 760. Will this be good enough?

I have 8GB of RAM and my CPU is an AMD-A10 6800k APU with Radeon(tm) HD Graphics.

Minecraft: How do you place a trapdoor on the front of a despenser?

I'm trying to make what looks like a cannon on a ship i'm building and want a trapdoor connected to the front to form a flap to open up for the cannon to fire. I've seen it done in videos but i can't figure out how to place it without opening the dispenser GUI.

Laptop overheating our of the blue

So, this is my laptop: http://www.amazon.com/...00CZ3CJIG/

And it's a beast. Up until 2 weeks ago, it ran perfectly smooth, didn't overheat much, and Minecraft ran flawlessly. But now, whenever I play Minecraft, I get random FPS drops where it goes down to like 10 fps for a few second, then back up to 200, then again a few mins later. And it overheats like crazy now, I can barely touch it when playing. Also, when playing, the entire pc slows down despite CPU usage and memory being at 20% and 50%.

I thought it might have been a virus, so I factory reset my PC but it hasn't changed. I don't want to spend hundreds of dollars at a repair shop, so can anybody here help me?

I also cleaned the fan with compressed air to no avail.
