Speed up the emulator

[Shonumi]

Dolphin doesn't use all that much RAM. In reality, as long as you have enough, RAM doesn't factor into Dolphin's performance. The CPU, on the other hand, is responsible for a lot of Dolphin's performance. If you want to see an improvement in Dolphin, get a better CPU. Your current CPU, however, looks okay for a lot of games. I suggest that you try overclocking it first, if possible, to see if you can manage full-speed on Sonic Unleashed.
