Right now there is no such way that 4-core support in pcsx2. MGTS made two threads for pcsx2 (one for graphics and one for all other stuff), so maximum number of cores pcsx2 could use is 2. With a little luck third core could be used for a OS needs, that improve speed 0.2-0.5%. So better way to use 4-cores is turn off 2 of them (it speed proc a bit) :-).

I remember ref telling me once, when I first got my Quad Core, I really excited and said I couldn't wait for Quad Core support. He told me most likely it will never happen, and I asked why.
He told me, on top of being a really difficult thing to do(Go back re-write A LOT OF CODE), the benefits would be nearly worthless and that keeping them in Sync with each other would be very hard. He said compatibility would go to hell, and MAYBE a speed boost of 1-3%.
So obviously, it seems not quite worth it.
