Short version:

Which processor will give me the most 'stable' processing power OC'd with some consideration of cost? (I.e I won't pay $500 more for .01% improvement :)  )

Long Winded:

This is a difficult question for me to ask the group because I have run AMD procs since the 486dx280, even had a NEXGEN in there. Bottom line is my 5600+ only OC'd
marginally and I'm not getting the FPS I want from the newer DX10 games, and I'm extremely disappointed with the new Phenoms. SO, Intel will infiltrate.

I have a relative that works at Intel that can get substantial discounts on the processors (they are alotted 1 a year). The QX9650 would be $450ish. I point that out since I don't want price to bias your answers, but also realize all procs will have a similar discount. I want the horsepower to run 3D games. My memory is very low CAS 1066 OCZ. I have no problem with OC'ing.

I know it's a loaded question, but which one do I get? You guys are the experts and hopefully can educate me on what I'm missing, or what the marketing dept isn't letting out :)  If I can push the QX9650 to 4.0 w/air and the 9550 only to 3.6, I think it's an easy decision between those, but what about the newer QX's?

I want a 45nm chip that has the full 12Mb L2. The QX97xx series is intriguing with the 1600FSB, but can the 9550 be pushed that far just as easy? The QX9770 has to have the X48 chipset, which seems to not be as tunable, but the QX9775 uses E5400 and a new socket and FBD?? The extremes have 130W vs 90W - I'll snap a thermalright Ultra 120 on it, so maybe the heat difference isn't important.

Thanks all.

I think the vga card is much more important for high FPS than the cpu.
Any of the mentioned processors would be fine with even the most powerful of vga cards.

I run my QX9650 @4Ghz only because I haven't had a chance to fiddle. People are getting remarkable oc's with this chip:

That's with the stock cooler he reckons 5 on bigger air. If you can a QX chip at a discount go for it, personally I don't know how you waited this long. As for the X48 it clocks higher and runs alot more stable, I recently got a GA-X48-DQ6 and its hasn't dropped once. If your happy with 4Ghz you don't need anything other than the stock cooler, it's a big mofo and actually overlaps one ram slot on my mobo.

Thanks for that link, gives me a lot more info.

I should have mentioned that I have 2 SLI 8600GT's, while not great are definately not my weakspot.
June 14, 2008 7:25:20 PM

I to have the qx9650 at 4.2ghz with a titan amanda cooler and found it very stable but the q9550 would be fine with a pair of 8600gt's i'm sure.$450 is a bargain for a qx9650 i paid more than twice that.go for it
June 14, 2008 7:57:41 PM

The QX9650 seems like a great choice, but what is surely hampering your system is the SLI 8600GT, you can be sure a single 8800GS would eat them alive.
June 14, 2008 8:21:09 PM

go with the q9550 and the rest of the cheese towards an 8800gt at the least is what i would do IMO. that would be the idea system at $500 overall if you get the q9550 for around $300 rather than $550!
June 14, 2008 8:25:59 PM

I know you'd hate me for this and i know that this is not what you want to hear ...but gettin a QX isn't worth it at all .... you won't notice any difference playing a game with an OC'd Q9300/Q8500 and a QX ......... bulk of gaming performance depends on GPU. Except for Fli Sim.
June 14, 2008 9:20:10 PM

If you have enough money, then get QX9770, or a QX9650, or a Q9550, in that order depending upon available funds. The QX9775 is a different platform and therefore very limited in usage, besides which, it doesn't do any better than a QX9770.

The above said, unless you're into heavy overclocking, the Q9550 will probably do just as well as a QX9650. The QX9770 remains in a class of its own. By the way, who told you that a X48 mobo isn't tunable? You get a good one, like the ASUS Rampage Formula or Maximus Forluma if you want DDR3 ram, or one from DFI, and you can tune it any way you want. I can get my QX9650 up to 4ghz on air, though things start to get fairly warm at that speed. Using a TRUE with two fans and the temps are quite manageable up to 3.93ghz on air. I do sometimes wish I'd have had the extra money for a QX9770, but choices have to be made, and the taxes have to be paid (IRS). Do be wary of the Nvidia chipsets, as they have had several problems, especially when overclocking, including corrupting the hard drive. Anandtech had a recent article on this: http://www.anandtech.com/weblog/showpost.aspx?i=460 Nvidia is claiming that they have solved the problem, but only time will tell for sure.

At the moment, if you want two cards, a pair of 3870s will do nicely. If you can wait a few days, the 4870s will be out and they should do better yet. But a question arised if you really need two cards. If your monitor is less than a 24" widescreen, than one card should do the job, especially if you got a 4870. One thing for sure, if you absolutely want to go with two cards, cut down on the CPU before you cut down on the video cards.

Q6600 FTW!
June 15, 2008 6:02:22 AM

@ Best_reviewss.... What is up with u ADDING the product numbers?? Does not make sense to me!! Products are NOT numbered according to any "power index"... Thats just a number givn to differentiate them!! Pls stop adding them... Its freaking me out!!
June 15, 2008 12:51:59 PM

q9975 = 18 + 7 +0.5 = 25.5 power index
q9970 = 25 power index
q9659 = 9+6+5 = 20 power index

Have any of u ppl heard of these processors?? There is no q9975 or q9970 or q9659.. Bseides, the qx9775 is a Xeon!

Anyways, I dont mean to upset you or anything... I just think "power index" is not really a valid technical term.. U cant just add up product numbers even if the processor is faster..
I mean just cos its named qx9775, it does not make sense to add up 9+7+7+5..
Just to go 1 step further.. If ur so called "q9975" has a "power index" of 25.5, can I add up 2+5+5= 12.. 1+2= 3.. So its "real" power index wud now be 3!! Did i get that right??? ;) 
June 15, 2008 4:11:41 PM

Thanks for the input. I've been around a while and have never heard of this power index math? Can you explain or link to something? What I thought was most likely a 9550 didn't pass the same benchmark tests as a 9770, so it was turned into a 9550? Possibly it tested fine as a 9770 but due to market conditions it had its variable multiplier pathway fried and labeled as a 9550.

It seems that on average a Q9550 can only OC to 3.8 whereas a QX9650 is at 4.1? So my decision between the two would be is a a 10% increase worth a 25% premium. I'm really leaning toward the QX9650. It is a Yorkfield XE which uses the high-k metal gates, whereas the 9550 is a standard Yorkfield. Ay? Anyone know what the Q9650 should have when released? The QX9770 looks impressive when comparing stock performance, but I don't see any significant differences when OCing.

No love for the skullrail chip?

My 8600Gt's definitely will be replaced, but when I put the two of them in my friends box with his q6600 My 3dmark and crysis fps goes up substantially. I do run a 24" LCD (preferably in 1920) and wanted to settle on the chip before changing the GPU for fear of any of those odd incompatibilities.
June 15, 2008 4:57:41 PM

For instance "x" boosts, "s" boosts a little bit and a new-memory7 type boosts, Every new technology as well as a cool-looking letter boost.

And here I was thinking I HAD to look at the performance, features and benchmarks!! When all I had to do was to add up the product numbers and look out for Xs or new-memory7 type!!
I am sorry, but it does not make sense to me... Maybe someone would like to help me out and clarify things.. Cos afaik, these are propriety terms from manufacturers.. And not meant to be added up or something.. I looked at your post abt GTX280 and I am as confused as before!!
June 15, 2008 5:03:38 PM

@premio... I wudnt worry too much about "power indexes"!! Whatever that is!! Just look at benchmarks.. Skulltrail chip (QX9775), is just a QX9770 modified to fit in a Xeon motherboard (like for skulltrail).. Apart from that, I would bet they are both exactly the same.. Except for pinouts..
And also, the qx9650 is more than good enough for ur purpose, and wudnt justify the extra cash for the qx9770.. But, for me all XTREME processors are not really worth their price.. But if u got the cash, GO FOR IT!!

Your current CPU is not by any chance the fastest, but is definitely not what is hurting you the most on a 1920x1200 res, you should REALLY take care of the GPUs before buying a new CPU.
June 16, 2008 9:32:29 AM

"Do not bother bying those extreme processors. Their power index is high, but is not comparable if we see the price performance ratio. No, never.
Go for a 9550 and overclock it. 4ghz and a power index of approximetaly 30 is what u can reach with that processor. I guess."

I am planning to build a new system. I would appreciate if somebody could answer these: 1. I plan to buy the ASUS Maximus II Formula. It supports FSB up to 1600 without OC, I think. Since the QX9770 supports the same speed. Does that mean a system with QX9770 will perform much better than a system with QX9650 or Q9550? For such motherboard, how the QX9650 compares with Q9550? 2. Supposing that the rest of the components stay the same, which one is quiet (QX9650 or Q9550)? Thanks.

unlocked c0 or c1 chips will alow better tuning by multiper and fsb

a c1 qx9650 and q9770 are the same cpu with different locked bus for auto - with manul mobo there is no dif.

the higher price is binned higher but for all you know some q9550 could be better bind
i think intel is saving the good bin chips for the q9650 release

Hey,

Hope you don't mind me asking, but what settings did you use on Bios to get the qx9650 to 4ghz on the ga-x48-dq6?

Thanks!
July 19, 2008 9:30:24 AM

"Since the QX9770 supports the same speed. Does that mean a system with QX9770 will perform much better than a system with QX9650 or Q9550?"

Yes a QX9770 will outperform a QX9650 and Q9550.

" For such motherboard, how the QX9650 compares with Q9550?"

The QX9650 has an unlocked multiplier making it an excellent overclocking cpu. If you don't plan on overclocking get a Q9550.

"Supposing that the rest of the components stay the same, which one is quiet (QX9650 or Q9550)? "

Cpu's don't make noise. The QX9650 comes with a much larger and much better cooler than the Q9550 so is therefore louder. The cooler that comes with the QX9650 is the best stock cooler I have ever seen or used.

"Hope you don't mind me asking, but what settings did you use on Bios to get the qx9650 to 4ghz on the ga-x48-dq6?"

I have workerd hard to get the right setting for my computer so I am hesistant to give them away, I actually have it running at 4.3Ghz right now but I will give you some tips:

CPU, DDR,MCH, PCI-e and FSB all needed to be overvolted. Some by only very little but that's all it takes to make the difference. The 4.3Ghz overclock is also made possible by the my case, the cosmos S which I absolutely love and has a 200mm side fan that sort of acts like a RAM/Northbridge cooler.
Good Luck!!.

on air you jugde speed by temp then you check apps - i heard the the qx9770 is hotter and not as good as the qx9650?

on water the qx9770 is faster? is that not correct?
July 20, 2008 6:24:56 AM

Even if a QX9770 was a well binned QX9650 it would still ultimately perform higher be it on air or water. You can't judge a cpu's quality by a few overclocks posted on the net, some people know how to overclock without getting too much heat into a cpu and some people just madly overvolt anything. When you see some of the high clocks on air compared to what others are getting, you realise this is true, even though some chips turn out better than others at the factory, the manufacturing process is so precise now that there is little between the higher end quads. So don't always believe someone when they say "you just got a bad chip"
September 5, 2008 7:03:24 PM

I'm not sure I agree with this. The qx9770 costs $1400 and the qx9650 costs $1000. The q9550 costs $330, which is 4 times cheaper than the qx9770 and 3 times cheaper than the qx9650. I build computers and customers ask "what do I get for that kind of money? Is it 4 times faster?" I can take a q9550 to 4.5GHz on water, which is faster than either the qx9770 and qx9650 at stock settings. You take that $670 or $1070 and get a good water cooling setup for $200 (Swiftech anyone?), OC it to speeds above either of the extremes at stock and still have extra cash for a great video card(s).

If you are strapped for cash, get the q9550; if not, go for the gold and get the extreme versions.

September 5, 2008 7:42:20 PM

Buy a Q9650. It just hit the Egg for $550. Unless you are a hardcore overclocker, their is never a need for the "QX" chip.
September 5, 2008 8:59:13 PM

Heh.. just buy skulltrail. Get 2 QX9770's with 4 4780x2, and don't skimp out on the PSU. :p 
September 6, 2008 1:33:38 AM

I agree with kaldor, get the new Q9650. It will save you a bundle from the QX, and has a higher multiplier than the Q9550. Use the money you save to buy a decent graphics card. You won't notice a gaming difference between any quad clocked over 3ghz. A 4870, or gt260 would do nicely though.
September 6, 2008 1:39:51 AM

i base it on market price not newegg price

qx9770 = $900
qx0650+ $700
q9650= $550

the qx9770 is more likely to be the newer stepping and can handle higher voltage better - if your looing for an extreme chip then your going to overclock it.

i am selling all most all hsf, water cooling blocks - i sold off the qx9770 stock.



ps:i sold all the qx9770 stock i had.

i kept a 4.2ghz water cooled qx9650 for myself.

wait for nehalem or buy a qx9650 on ebay for $600 or less or if you will not do that then get the 9650
October 11, 2008 6:18:28 PM

Not taking into account Ebay prices - What is better: getting a Q9550 and a some serious overclocking equipment or a QX9650/9770?

I ask this because for the price you can get:

Q9550 for $320 on newegg + an Asetek VapoChill Lightspeed (phase cooling for cpu) for $800 and then overclock the hell out of it (not sure how far you can take it though).

or:

a QX9650 for $1000 / QX9770 for $1450 + whatever you can afford after that

I then wonder if it is really worth this if you are going to do overclocking because if I spend that extra money on an awesome watercooling or phase cooling kit I can always keep it to play around with next gen. AMD/Intel cpus. If I spend the cash on the hotter cpu models, I lose the investment once I have to buy a newer and badder version. (or I fry it :pt1cable:  )

For me it would depend on how the cpu improvement (overclock) will scale with high end gpus (4870 X2, 280 GTX SLI or 4870 CF) and the long term investment vs. performance consideration. For me the improvement should at least be a 1/3 to 1/4 ratio performance increase to improvement cost when using the newest gaming software in order to even consider it. This is why I even wonder if it is simply better to just get an E8500 or Q6600 and splurge on a OS kit and case?

Go with the Q9550 get 12mb L2 can OC around 4ghz if willing, total stability, i went from a dual core opteron 170 which is still a half decent proc "dont laugh" Oc at 3.2 with dual 8800GT. example grand theft auto 4 with dual 8800gt's which it doesnt work with SLI anyways with 4ig ram on a A8N Fatality SLI mobo 23 24 fps went to Q9550 with one 8800gt same amount of ram went up to 45 50 fps with stock settings no OC for the money Q9550 blows away the rest
