Is My Computer Fast Enough?

[NovaNights]

I bought a new HP Pavilion desktop from Best Buy and they told me that it was an above-average gaming computer and it does play most new games at decent settings. I can't get Dolphin to run at more than 60%. I have tried Legend of Zelda: Twilight Princess and Spyro: A Hero's Tail.

System: Windows 8.1 x64

CPU: AMD A4-5000 w/ Radeon HD Graphics 1.50 GHz (Quad-Core)

GPU: AMD Radeon HD 8330 (DirectX 11)

Memory: 6.00 GB (5.45 GB usable)

Emulator: Dolphin 4.0.2 x64
