Would the Intel Q9450 good  for the EVGA 780I

i already have a 780I should i get the Q9450 or just go with the E8500 (using for gaming and maybe some 3d model design) but Gaming Overall.

Yes, Q9450 will run fine on that board. You might need to update bios though.

Q9450 would certainly be better than E8500, especially after more quad optimized applications came out (there are few of them at the moment). But it'd cost more, so it's not a fair comparasion. Keep in mind 780i runs at 1333mhz fsb natively, and oc reliably to 1600mhz, which is 3.2ghz oced for Q9450.

i would use an intel mobo if you want max oc
 
you get 3.4ghz with the 780i which beats the 3.2-3ghz you get with 680i

You will never get 3.2ghz on 680i with Q9450 with its 8x multiplier. Of course, that's a moot point, since it doesn't support Yorkfield.

I beg your pardon,
 
My Q9450 is at 3.4 on my 680i at this very minute, been there for 5 solid days.
 
The best board for the Q is the 790i Ultra or SLI, it smokes on them....
 
Bios P31 and P32 support the new stuff.

Yes, Granite3 you are correct.  Both the 680i and 650i chipsets now offer support for the new Penryn CPU family (dual and quad core).  Most of the motherboard manufacturers have released new BIOS revisions that allow for recognition of the new CPU microcoding.  Tomshardware had the unfortunate timing of conducting an extensive study into this very issue BEFORE most of the motherboard manufacturers had their new BIOS revisions ready for release.  Their original findings are no longer valid.
 
I am running a Xeon X3350 (Q9450 clone) in an eVGA 780i SLI motherboard (BIOS version P04) and a E3110 running in an Asus 650i SLI P5N-E motherboard (BIOS version 0901).  Zero problems thus far and I have run extensive benchmarks (3DMark06 looping for several hours, and Prime95 running for several hours).  Rock solid stable.  Both systems recognized the CPU immediately and proceeded to boot into windows normally.  The only catch was that the first time I booted up the Vista OS installs (64-bit Ultimate and 64-bit Home Premium) required a restart after new CPU drivers were installed.  No big deal.  The system restarted and all was well.
 
And no dagger, I have read several hardware forum posts will validated screen shots showing the Q9450 and X3350 CPUs overclocked easily to 3.8 Ghz will only minor voltage bumps.  Please do your homework before posting "bad poop" on forums...

3.8ghz on 8x multiplier with 680i or even 780i will not happen under normal conditions. "Extreme" setups are not useful if it can't be duplicated in the home. 1600mhz fsb is reliable oc, all 780i and p35 chipset boards should be able to hit it. Anything above is hit and miss, and shouldn't be counted on.

Please do not deceive people into overestimating the capacities of chipsets based on unrealistic pro setups.

Running a Penryn at 3.8Ghz is cake.  Just because you bought a sour mobo doesn't mean it can't be done.  
 
I can run my X3350 easily at 3.8Ghz with only a small bump in my voltages (1.2V to 1.4V).  475 x 8, FSB at 1900Mhz and all is rock stable.  Prime95 for hours - no problem.  Running Crysis at 1920x1200 on VERY HIGH SETTINGS in Vista (AA disabled) - no problem.
 
And I don't have any kind of "pro setup".  What is that all about?  Are you talking about Phase-change cooling?  Liquid cooling?  Voltage mods?  What?  Be specific.  Regardless, my setup is anything but pro.  Yes, it is a nice system, but it is entirely "out of the box" and air cooled.  The only aftermarket item I am using is my heat sink fan, a Thermaltake V1 copper heat sink.  Here's my setup:
 
Intel Xeon X3110 dual-core Wolfdale CPU (333 x 9 = 3.0Ghz, 1333Mhz FSB, 6MB L2 Cache)
eVGA 780i SLI motherboard
Thermaltake V1 heat sink fan
4GB (4 x 1GB) Super Talent DDR2800
Thermaltake Toughpower 850 watt power supply
2 x 8800GTS 512MB cards in SLI @ SSC clock speeds (700/1750/2000)
Antec 900 PC case (Rev 1.1)
 
As you can see, I don't have a super system, yet I am able to overclock like crazy.  So, I'm not sure what to tell you about your assumptions regarding overclocking the Wolfdale and Yorkfield Penryn CPUs with a 680i or 780i chipset equipped motherboard other than your wrong.

I wouldn't take what this person says very seriously. Feel free to buy the hardware and try, but you won't find him/her when you can't oc that fsb to 1900mhz.

You should search for benchmarks (instead of extreme setups intended for bragging) before listening to this Nvidia fanboy.

dagger, just look at the system you have - an outdated X38 chipset motherboard.  I rest my case  Upgrade to a X48 chipset and then we can talk.  Too bad the G45 chipset has been delayed for the time being...
 
And yes, the 780i chipset can overclock very well.  The 790i overclocks even better.  DO YOUR HOMEWORK before calling it quits for everyone.
 
I am no fanboy.  I go with whomever has the better product.  I've switched back and forth between Intel and AMD and nVidia and ATI for years.  Why?  Because I am opened minded and will go with the better product at the time I want to purchase.
 
Oh, and you know you can overclock your q6600 higher than 3.6Ghz...that tells me you don't know what you're doing when it comes to overclocking....my friend has his at a rock stable 3.8Ghz @ 1.45 Volts.  Food for thought.
 
And you want me to provide a thread showing folks are overclocking their E8400s and E3110's past 4.0GHz?  Here you go!  http://forums.anandtech.com/messag [...] id=2164762
 
And a pic of someone overclocking their X3350 to 3.8GHz @ 475 x 8 with a 1900Mhz FSB...and yes he is using "only" air cooling:  http://i235.photobucket.com/albums [...] stable.jpg
 
Back to you dagger...    
 

 
Uh.... http://en.wikipedia.org/wiki/List_ [...] 2_Chipsets says the X38 was released 9/23/07.  While it has been superceded by the X48, it is not in any way "outdated."  

P35/780i fsb run at 1333mhz natively, and oc to 1600mhz reliably.
X38/48 fsb run at 1600mhz natively, and oc to 2000+mhz reliably.

Ignore the fanboy, he's here to argue, not to help.

 
Yes, that was 8 months ago.  Okay, "outdated" is a bit harsh.  Regardless, dagger doesn't seem to understand that it is quite easy to overclock the new Penryn based CPUs.  I was being sarcastic more towards him than the X38 chipset.  His only non-intellible response is to call me a "fanboy" rather than to do his own homework.  He thinks that you have to have an extreme set-up just to overclock.  Also, he can never get his facts straight.  Case in point, he stated the X38 (along with the X48) has native 1600Mhz FSB support.  This of course is NOT true.  Only the X48 has a 1600Mhz FSB support and so will the G45 once it is released.  The 790i nVidia chipset already has this capability as well.
 
Enough wasting my breath on dagger...
 
So, snarfies1 what is your computer set-up?  Just curious.  And do you do any overclocking?

 
Where's YOUR proof that the 780i chipset can't overclock Penryn CPUs past 1600Mhz dagger??
 
Still waiting...    

There is no proof that it can't do more than 1600mhz fsb, but there is also no proof that x38/48 can't do more than 2000mhz. Most can, but the worst model among them cannot. It's just above those speeds, successful oc is not guaranteed. "Reliable oc" means basically guaranteed oc, that can be duplicated time and time again on different setups. "Extreme oc" are those done by pros that cannot be duplicated at home.

For hardware buying purposes, reliable oc is the only one to count on. If it does better, good, if it doesn't, it's to be expected.

People who ask for advices here don't care for your boasting of your favorite brand. They only want good, reliable advice, concerning specs that can be counted on no matter what. You're here for yourself and your own ego, not to help others, please go away. I've wasted enough time on you.

 
Oh, I see.  So your whole problem was that what you think is what the rest of the world should think too.  Ahhhh.  Now I understand your ignorance.  lol  I hate to tell you that overclocking the 780i beyond 1600Mhz FSB IS THE NORM and CAN be duplicated RELIABLY EVERYTIME.  So you go away.  I have my facts straight and you have your opinion wrong.  NUFF SAID!!

Fanboys like you are here for your own ego, and provide free advertisement for your favorite brand, not to help others. When the people you give your ill advices to can't reach the speed you claimed, where would you be?
