The fastest AMD APU Quad Core A10 5750M is only on par with low-end Dual Core i3 2330M

Keep in mind that Dolphin is Dual Core application , a Quad Core that is on par with Dual Core will perform even less FPS in Dolphin

In the end, I bought this one http://shop.lenovo.com/us/en/laptops/ideapad/y-series/y410p/?sb=:000001C9:0000FCD2:#customize
I know dolphin is CPU intensive but will it run tales of symphonia, skies of arcadia and wind waker in playable speed with this one?
The laptop's specs are:
CPU- 4th generation Intel Core i7-4700MQ (2.40GHz 1600MHz 6MB)
GPU- NVIDIA GeForce GT755M GDDR5 2GB
RAM- 8.0GB PC3-12800 DDR3L SDRAM 1600 MHz
Also it is running Windows 8.1 64bit. Do you recommend me to downgrade to Windows 7?
