big deal who needs 0.9.7 Tongue
I'm inactive on this, dedicating most of my time to osu!

i don't think so.
have a look there http://code.google.com/p/pcsx2/
CPU : I7 2600K Oc'ed @ 4.2Ghz
Mobo : Intel P67 southbridge
GPU : NVIDIA Geforce GTX 750 Ti
RAM : 6 Go

To clarify what jesalvein said (in case the OP didn't understand) PCSX2 only requires 1-2 Gb of RAM depending on the OS, so there is no point to code for 64bit when it won't take advantage of the extra RAM. Furthermore, from my experience with the pre-alpha revisions of 0.9.7, it's a nice improvement, more user friendly for new people, and I have seen definite speed increases in the games I have played.

We dropped 64bit support some time ago, as it was a problem to manage and cluttered the code a lot.
What was there wasn't working much anyway.
We do consider re-adding it, but it'll definitely come at a later point than for the 0.9.8 release.

In any case, what's the real advantage of PCSX2 having 64-bit support aside from being able to utilize more than 4GB of RAM?

less opcodes in the recompiler in some scenarios, a lot of the R5900 commands are using 64bit's of registers, sometimes we have to handle these manually in 2 parts (unless its all SSE now, i havent checked).

so there would be a potential 50% improvement in speed there (note i mean per opcode, not overall)

That makes me wonder... How much of a speed boost can be expected if plugins (let's say GSdx) were using 64-bit? I'm pretty sure 64-bit plugins be usable in pcsx2's current state but what if the plugins were separated into (puts up a flame shield just in case) separate processes when a game is active? I'm not sure how separate processes for plugins will effect performance and syncing since I really heard much about this idea to utilizing quad-cores (I still have a dual core so it wouldn't matter to me).

Probably none at all, as far as im aware, nothing really on the GS side requires anything above 32bits, besides most of the GS side is literally DirectX/OpenGL handling.

I'm interested to see what they add in future releases. I'm very happy with the pre-alpha right now.
