Choosing the right CPU for the job...

Hello,this is a semi-relevant question to the emulator.I'm not even sure it belongs in this forum but since CPU plays a major part in performance of the emu,I just wanted to be sure.

I am upgrading my PC and I've come up with some ideas but I have trouble deciding which one I really need.

1) E4500 2,2 GHz,800 FSB 108€ (my original choice)
2) E6550 2,33 GHz,1333 FSB 149€

(this has higher FSB and slightly higher timings,costs 41€ more than the previous choice but I think this strikes the golden balance between money and performance)

3) E7650 2,66 GHz,1333 FSB 170€ (at 20€ more than the previous option,I get +330Mhz,this being a Dual Core I end up with 5,24GHz instead of 4,66 GHz.I think I could casually clock it to reach 5,50Ghz or maybe even 6)

Of course,this is also an option :

4) Q6600 2,40 GHz (9,60 total oO),1066 FSB (I don't get why it has less FSB than its smaller brothers) 240€

I consider the Quad-Core overkill but heck since I can get it with only waiting an extra 15 days,this is also an option.Of course I could benefit from its performance but like I said I think it's overkill but I'm no expert.

I'm "upgrading" (building a new PC step-by-step over my previous setup is more like it) and plan to use

- ASROCK 4COREDUAL-SATA2
- CORSAIR TWINX DDR2 6400 CL5 2GB (2X1GB) DUAL CHANNEL KIT
- 1xGAINWARD 8798 BLISS 8600GT 1GB PCI-E RETAIL (best 8600GT there is I think)

So now you know the system specs you can make an informed suggestion :cool:

Can anyone inform me with regards to the FSB and why would I need it to be as fast as possible ?

Also will an OCZ GameXstream 600W cut it in supplying enough power for that system ?

sorry for tons of questions :innocent: !! Getting a new PC doesn't occur often !

get the Q6600 if you want 2 future proof it but quad-core is slower than dual core in gaming due to lack of Support for quad core at the present(newer releases support the quad core)... also pcsx2 doesnt support quad-core. And about the 1xGAINWARD 8798 BLISS 8600GT... get ASUS en8600GT tests from pc-world suggest it seems 2 be the best. Check power supply needs here...... eXtreme Power Supply Calculator Lite v2.5

Ok, some tips :p
Never add up the cores Mhz to guess its speed, its not working this way.

What processor (and mainboard) to get depends a lot on if you're going to overclock it.
The E6750 is currently a good choice at stock performance and can be overclocked quite
well. Personally I don't recommend getting a quadcore now, 4 core support is bad and they
do not overclock that well.

Then : the mainboard is crap, totally useless for overclocking and performance tweaking :p

If you have the time you should wait for the new Penryn based processors. They
should be available soon. These chips run cooler, have more cache, clock higher, etc..

In terms of emulation get as high a clock speed as you can afford.
I have an E6850 overclocked to 3.7 ghz and FFXII still drops below 60fps in a lot of areas (both cores are floored at 100%).

Don't bother with quad core yet. Almost nothing supports it, and by the time you start seeing anything that does, it'll be time for another cpu upgrade anyway.

This is because the processors aren't from the same release line. Initial C2D CPUs where E6300, E6400, E6600 and the Q6600 (Quad)
A little later they expanded the line with "cheapskate" version of the Duos in form of the 4xxx series (less L2 cache) and more Quad Core models (Quad Extreme)

The XX50 series (6550, 6750) is the first real enhancement to the "plain" C2D's. Raising their FSB to 1333MHz.

The next step are the about-to-be-released E8XXX and Q9XXX series, featuring 1333FSB, 45nm manufacture and enhanced Cache.

If you want overclocking that e4500 would be nice, it has a x11 multiplier which makes it so even just at 1066 FSB it'll have a raw power of 2.9GHz which is very good for PCSX2

if u dont want to overclock and want the best performance for every app on your PC not just PCSX2 E7650 would be your choice it has 3MB cache L2 which is nice and still faster than the others at default speed

you could also wait for the 8xxx and 9xxx line but those are just more cache which isnt that much necessary after 4MB :p

4) Q6600 2,40 GHz (9,60 total oO),1066 FSB (I don't get why it has less FSB than its smaller brothers) 240€
this is the perfect example of why u shouldnt add the total GHz of all the cores, it may theorically have 9.6GHz but since most (almost all) apps out there wont take advantage of all cores the theorical 9.6GHz are useless (PC games nowadays are still being released as single core and dual core at best)

AMD cpus are best unclocked.

Intel cpus are best overclocked. A good thumb rule.

Get the Q6600. Quad core. Are you going to play pcsx2? PCSX2 ONLY? PC GAMES?? In future, more pc games will support quad.

Atm Crysis, Lost Planet(?) supports Quad.
You can always play ps2 games on ur console.

And it's VERY easy to overclock a Q6600 with G0 step. Many people managed 3,2ghz wihtout setting any higehr vcore!

if its a choice between all of those id go for the Q6600 any day of the week. Make sure your gettings a G0 stepping model because those overclock amazingly well. People say they Q6600 is overkill but I used to have a dual core before hand and you do notice the difference, some games use it. When running PCSX2 3 cores are normally. When it comes to value for pure cpu horsepower you cant go wrong with the Q6600

Sure you can. You can get far more clock speed, something that is much more of a benefit in PCSX2, for the same money with something like an E6850. It's not often anything takes advantage of dual cores...and it's rare as hell that anything out there takes advantage of four. A third and fourth core is next to useless now with the exception of maybe the cryengine and will continue to be for at least the next year or so.

I'd say xx50 CPU line is the best bet moneywise right now. I'm running PCSX2 on 6850 @ 3.4 - sweet and fast, at least most of the time. Q6600 architecture looks kinda half-baked to me (quad core vs. temperature and voltage + low clocked).
Anyway, whatever you do just DON'T BUY an Asrock mobo!!, unless you need 0 oc possibility or wish to get the rest of your components fried - that's the biggest crap i've ever seen.

I got my Q6600 for ÂŁ150 and got a chip thats each core runs at 3.8gig on air cooling, and could probably go faster with more cooling. Thats 15.2Ghz of processing power. Sure you point out most things dont take advantage of the extra core but running multiple applications can.

I regularly play ff12 on pcsx2, while on another monitor from the same pc have videos playing downloads going etc. Sure without over clocking it wouldnt be nearly so good, and I would have been better spending the money on another chip but when you over clock the q6600 thats when its true value is.

He's right though if your gonna over clock to any real speed you need to get yourself a decent motherboard, asrock make a good board just not good at clocking.

Yeah, it's pretty much a question of individual experience - mine was seriously bad with Asrock for most of its products, and not only mine. But it does not matter. My point is we're talking here about high end Wolfdale C2D/C2Q CPUs and so on and I guess there's not much point in putting a good CPU into a really low-end piece of PCB with very limited capabilities - you won't squeeze much juice out of it. Get yourself a P35 ASUS/ABIT/MSI mobo - they've got what it takes when it comes to OCing + they're a bit more future-proof.
