I got an Intel i7 920 as well and the emulator works ok on most games (ok means 20-30 FPS average). PCSX2 runs better on my machine though.
Dolphins major problem is that it only supports 2 cores, which makes an i7 920 (non overclocked) inferior to a good Core 2 Duo. According to the devs there's no way to deliver better emulation using 4 (or more) cores, so I doubt we'll see at least Quad Core emulation very soon...
