It generally helps if you show us your configuration, and what the current speed you are getting but my advice is to simply try fiddling with the speed hacks, and keep on trying a variation of different settings. Read the descriptions of what each do and see what you can come up with. But from what I gather try:
-Setting the frame limiter to off and perhaps use the frame skip, which might give you a bit of help
-Under the CPU settings (I think) try changing the speed hacks by increasing their usage
-Under GPU settings, if you have the option set them to DirectX 10 and ensure that you are running the game at native resolution. having this turned off will make the game look prettier, but will demand more power.
Also with the beta version, can I assume you are using the 1888 version listed at PCSX2.net or are you using a user compiled version? Either way perhaps trying a different version to determine if the compiled beta you are using may have issues.
Finally if all of this is unsuccessful then you must chalk it up to your processor and GPU being a bit slow, although I run T7350 at 2.0ghz and a 9600Gt, some games run excellent (Tenkaichi 3, Viewtiful Joe 2, Godhand) whereas others (Jak and Daxter 3, Grand Tourismo 3, Sonic) all run rather crummy.
