How to get more FPS for minecraft?

Whenever I play Minecraft (1.7.5) it always lags. What I mean by lag is that I get 5 fps on average, literally. I have tried to give it more ram, set the priority to high, set the video settings to run faster, and I still get 5 fps. As of now, Optifine hasn't been released for 1.7.5, and Optifine is usually an update below the current version. Can anyone help me?

How to play with no lag on PC?

I recently bought a new gaming pc over amazon for $1000 and it really sucks in the "gaming" department. Whenever I play games that I've bought over steam, they lag like ****. Whenever I play any game it lags immensely, probably around 15-20 fps. In certain features of the game the fps is literally like 5 fps, such as zooming through a scope of a gun. The only game I can play that has no lag is Minecraft.

What should I do in terms of speeding it up to maybe, i don't know something like 80 fps?
Should I buy any better hardware? Is my RAM bad or my graphics card?

Do colored sheep spawn in Minecraft?

This may sound like a stupid question, but bear with me here. I know animals don't breed unless I feed them but if I had blue sheep inside a fenced in area, would blue sheep naturally spawn in the same general area outside the fence. I keep seeing colored sheep (blue, green, red, etc.) running around outside the fence, but I don't seem to be losing any sheep. I have my fence two posts high if that matters.

What laptop would you recommend for gaming and recording at the same time?

I'm looking for a laptop that i can use for gaming minecraft on the highest settings and recording at the same time. So i was just wondering if you could recommend any laptop. I was thinking about MSI GE70, but maybe you have some other ideas. And it also has to be about 1500 US dollars.

What the heck is this thing? (Minecraft thingie)?

I was making a circus thing and while I was building it I blocked up the door with iron blocks (It was creative mode) there were some rainbow sheep in there, one named Dinnerbone, one Grumm, and one jeb_. I also had a creeper named Boomie in it. I deleted the door to get out and two of these things went everywhere. This is just a picture of one of them, and its squirming around in that hole. It doesn't seem hostile (Of course, I'm doing creative mode and I tamed a zombie pigman, enderman, and a friggin creeper) and its quite fast when not stuck in a hole.

What's it called? I'd wiki it, but then I'd need to search its name and that I don't know.

I chose the category because Minecraft is entertainment. HIGH CLASS. PIXEL-Y. ENTERTAINMENT.
