PS2 Emulator

Can anyone link me to a PS2 Emulator? You may think I'm being lazy but I want to get (possibly) the best one, if there is more than one.
I would also like to know if this computer could run a game such as crash bandicoot on the emulator.

Motherboard - ASRock Z77 Extreme4 LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard
GPU - GIGABYTE GV-N660OC-2GD GeForce GTX 660 2GB 192-bit GDDR5 PCI Express 3.0 x16 HDCP Ready SLI Support Video Card
CPU - Intel Core i5-3570K Ivy Bridge 3.4GHz (3.8GHz Turbo) LGA 1155 77W Quad-Core Desktop Processor Intel HD Graphics
RAM - 4GB DDR2

Those specs should be quite enough for PCSX2.You can download it from their official website:

Thank you for the help. Appreciate it. On this first time setup, should I leave everything at the default? http://puu.sh/1Euvh

On the first time setup should I leave all the settings the way they are or pick certain things from each one?

Is it possible to play with only a keyboard? I'm getting an adapter to use xbox360 controllers soon, do I have to wait until then?

Yes.But some first person games won't be controllable due to the need of R3 and L3 and analog sticks for aiming.But you will be able to play them.
But i reccomend you to wait for your Xbox360 adapter.

Would this work / be recognized by the emulator if I got this one?
I would be using a Official XBOX360 Black controller (wireless) , nothing special about it or offbrand, etc.

I have tried searching for any microsoft official ones but it seems they are all discontinued.
