The hardware specs you give are more likely to give a proper 720p 30-50fps.
Explanation: Many people here tends to think that a better processor is a must for good emulation. True, but you also forgot the RAM and paging file.
RAM : 8Gb : minimum fot emulation to be honest. 16gb is great (I have 16gb ddr3 and I run BOTW on 1920x1080 @144hz with an average of 70-100fps. My CPU is an Intel Core i7 4790k)
What I recommend you :
Create a paging file on drive C (where your operating system is installed) of 16384MB (16 384 is what you must type).Get a shadercache for the game(s) you are emulating and disable antialiasing in games.
Best luck!
