it is not old

You shouldn't get offended, PCSX2 requires a fast dual-core CPU. You've not stated what CPU you have, but the clock speed implies some kind of P4 (because a 3GHz Core2 is quite high end, not reflected by the rest of your system, I'm assuming you have a P4) which won't cut it. 4 year old tech and single core.

The RAM is low, bare minimum should be 1GB, though 2GB would be ideal. But this won't have massive impact on PCSX2 as long as you have 'enough'.

And while PCSX2 doesn't rely so much on GPU (I use an 8400m GS), it does require a GPU that isn't a bottleneck, which yours could be.

So it really will require a new system for you, I'm afraid, because pretty much everything needs to be upgraded (a CPU upgrade would require a new motherboard, for example).

The new RAM will help general computer performance quite a lot, so it wasn't a waste of time, but it was never holding back PCSX2.

PCSX2 really requires a dual core CPU, which your motherboard probably doesn't support. You're out of luck, I'm afraid.
