Problem, lag and acceleration with GTX580, i7 965EX

Dolphin is a lot less CPU intensive than this emulator, mostly because of how the PS2 was made. I would recommend that you try speedhacks. Not much more you can do than that than overclock or upgrade to a faster dual-core CPU.

indeed,3.2 ghz is enough to get playable speeds with this particular game, but not enough to get it running flawlessly, even when using gsdx hardware mode.
To avoid glitches, use software mode, but you will then need more than 4.2ghz to make it run @ playable speeds.

if i change CPU, it's not a upgrade, it's downgrade... I have the fastest plateform aviable... :/
With OC @3.8ghz, dosen't change.

It's the fastest class, yes, but you can certainly find faster CPUs, especially dual-cores.

For example, here is one:

That one is a quad core, but for example, you could OC it to 4.2Ghz. Which, according to Jes, would run the game at full speed. In fact, it would probably be easier on the CPU because it has more threads to render from, although I don't know much on the subject. Of course, there are probably much better and cheaper dual cores for doing this if you take a look.

Just to sum it up, you are not going to run at full speed on software mode unless you overclock or upgrade or PCSX2 gets faster. Sorry.

What's that? Faster than a 2500K @ 5.0Ghz, you say? lol

Sometimes you actually need Speedhacks. No processor available is god. Plain and simple.

Also, do you run with Hyper-threading on? Humor me, and disable it.

indeed, dolphin is much more System ram bandwidth limited.

I think what he means to say is that he has the fastest processor for programs that utilize his extra cores or hyperthreading. Concerning gaming and PCSX2, the 2500K is definitely faster. But I think what he is experiencing is similar to the issue I was having. In Valkyrie Profile 2 my fps would be about 50 when running through certain areas, but otherwise would be a steady 60fps. My CPU usage would only be about 80 percent on all four cores after testing all the different settings when the fps were at 50. By enabling VU stealing it will say I am getting 60fps, but will actually slow down worse than when it was at 50fps. So it seems that at the moment on the user side there is nothing more that can be done. And from what this guy is saying, it seems he is having a similar problem, unless he did not properly test out all his options in PCSX2 settings.

That doesn't mean it'll be enough, though...
Some game would require a CPU that doesn't exist yet to run @ full speed

you have the platform with the most cores, its not necessarily the fastest.

infact, not only is the Core i7 2's 10% faster core for core, they also have twice as fast dram latching for dram writes, allowing systems with 1333 modules to keep up with the i7 9xx using DDR3 1600.

Liquid Nitrogen overclock 8GHZ has to be king. I hear xeons are really good.
