* A Faster CPU will always give you better performance.
* A decent GPU is equally important: AMD GCN (R9 270/X or better) or NVIDIA Maxwell (GTX 970 or better, 960 is NOT recommended).
NOTE: AMD GPUs perform much better with the D3D backend and are much faster at integer calculations.
* The Direct3D backend is *much faster* with EFB to RAM
* Adjust your driver / OS / Dolphin settngs properly: GPU Peformance Guide
* For even better EFB2RAM performance, use the latest Unstable version of Ishiiruka (with the 'Fast EFB Access' setting enabled) instead of the latest dev. build.
* EFB2RAM gets more demanding as the internal resolution increases. Reduce the the IR for better performance.
