GTA SAN ANdreas on PS2

Hy! I am new at this thing and I wanted to know if there is an PS2 emulator for the game GTA San Andreas.And if there is where do I get it.
A friend of mine has a PS2 and also this game and I can borow it from him but is it worth it.(I have a DVD player that suports DVD-PS2)

My specs are:
AMD Athlon64
Geil DDR 1024MB
Geforce 6800

If I use any emulator will it be playable?
Thank You!

Though you have a powerful system there are still no Playstation 2 emulators capable of running games at a playable level yet.
