PS1/2 I'm getting low FPS on my PS2 emulator

[Renivere]

As you can tell from the title, I'm having troubles playing my games on my PS2 emulator due to low frame rates. My games are mounted in ISO format. My specs are:

Processor: Intel® Core™2 Quad CPU Q6600 @ 2.40GHz
RAM: 6.00 GB
Graphic Card: Radeon X1650 Series
Chip type is ATI Radeon graphics processor (0x71C7)
Operating system: Windows vista 64 bit

I'm using version 1.0. The only non-default settings is what I did above, checking everything in the speedhacks.

I downloaded a plugin that was supposed to fix the frames but it didn't and turning off FPS limiter only made it run at 900 FPS. My frames usually go as low as 26 sometimes and it turns really slow and scary

Ur GPU sucks, that's why.

I had a similar config a few months ago, a GPU upgrade (6450) would help.

Yeah I have a pretty old computer. It usually runs fine and things load quickly and work just fine. I've just been having troubles with the PS2 emulator frame rate (I'm using PCSX2 if that helps)

Your processor is not that great, so that might be the problem. Take a look at this: http://forums.pcsx2.net/Thread-CPU-Benchmark-designed-for-PCSX2-based-on-FFX-2
You CPU is pretty much all the way at the bottom of the PAL list, 34 FPS. Still, that's a heavy game it seems and 34 is still significantly more than 26.
I'm not sure how much the GPU influences things, so that could be the reason as well.

I'll try picking up a new GPU and seeing how things work out. Thanks for the quick replies and help!

Any recommendations on GPU? I'm not too tech savy so I'm not sure and the people at Best Buy don't always offer the best help.
