Games look choppy after upgrading to better harddrive?

Every game either on steam or off the internet downloaded runs at 60fps+ and is a choppy. Now I upgraded my harddrive from a regular 5400 rpm harddrive to a 7200 rpm hybrid drive.
I always use vsync and with it off is worse.

Specs: GTX 660m
i7 3610qm
windows 8
asus laptop

Before i got the new one it was smooth.

The funny part is in my emulator I use it works fine for gamecube games. Than I play minecraft, call of duty, and than steam games do this? How do I fix this?

It won't let me upload a video but it isn't lag it is more like stuttering.

Turn off power savings for your gpu and set your power plan to high performance and make sure its plugged in.

Maybe it is just the CPU not working at high performance, but I know gamers that need 64 GB RAM too (you probably have about 8GB). You might also need to check on your graphics card, did you do diagnostics on it?
