If you're wanting to play android games on your PC, then the Android Studio emulator won't do.
I'm running BlueStacks and Nox on my AMD Phenom II X3 720BE (I have the 4th core unlocked). It's OC'd to 3.2ghz (from it's default 2.8ghz) and I was able to run BlueStacks VERY smoothly whether I was at 2.8ghz or 3.2ghz.
My GPU is an nVidia GeForce GTX 560. I think what's hurting you is the 2-core.
You need to remember. The emulator has to use your resources to emulate whatever it is emulating in addition to running the software.
