Will PCSX2 work best on my pc?

[Sousou13]

Hey, guys !! 
Just got a quick question here about the emulator.
Exactly how will it work on this pc:
CPU: Core 2 Quad Q9650;
GPU: GTX 650 1GB;
RAM: 4GB.

How much speed will it have? 
I doubt I'll be playing any other game than: KH I, II, Avatar

The recommended single threaded performance for most 3d games is 1600 but your cpu has 1265 points acourding to passmark
KH1/2 are not that hard to emulate,I even reach 40fps on KH1 on certain places on an at least 10 years old cpu which has at least twice lower performance than your cpu
