is that the dual core 1.7ghz cpu if I am correct it is a i3-4010U which is a low power chip. You should be able to run some games fines but if you are wanting like SSB or mario galaxy, xenoblade chances are you are probably going to run it around half speed which isn't fun. I can't tell you what games you can and cant play though there are probably more games that you won't be able to run at full fps then games that you can. I never tried using a laptop for dolphin so I am not very versed in what kind of cpu from a laptop is needed.
