> Intel Quad core QX9770 with DDR3 1600 RAM or go with a dual Intel quad core QX9770 with DDR2 800?
What do you mean? QX9770 = QX9770. No difference. If you mean a comparison between ONE QX9770 and TWO QX9770's, that's easy. The latter solution is not possible.
So your choice is, given QX9770, between 1600 or 800 RAM. That is not difficult to figure out.
yes they have dual quad core setups (8 cores). Intel offers it. http://www.newegg.com/Product/Product.aspx?Item=N82E16813121330
Did you notice that is ONLY for 771 sockets? You can try to fit in a 775 CPU, but chances are that the four missing connectors are for each of the cores, rendering them out-of-order.
actually yes, i noticed that mistake after i posted it. but my question still would be the same. would more processor cores or faster memory help speed up the rendering and overall performance of CS4?
That would require Xeon E54xx Harpertown's on a Seaburg 5400 mobo, and yes, you would benefit more from two quad cores than an increase in FSB from 1333 to 1600. Mind you, those mobo's are rather specific in memory requirements and do not allow 800 FSB's, at least not according to approved and tested memory sticks. The mobo you linked to would not be a favorite of mine.
So do you think it would be better to go with a server motherboard than a traditional desktop mobo? Will it fit in a universal case such as Antec twelve hundred? http://www.antec.com/usa/productDetails.php?lan=us&id=15120 sorry i haven't done any research before on server hardware. Thanks for your help.
IMO, yes. Will it fit? I don't think so. The case needs to be able to accomodate an eATX mobo and their site does not mention any specifications. There is however the Enterprise Server chassis that does allow eATX mobo's. Another consideration is PSU and mobo combo. As you have seen from the Intel Skulltrail mobo, the biggest problem facing users was finding a good PSU with the right connectors. I think you better investigate server cases, mobo's and PSU's a bit more. A good place to start is Supermicro, especially the X7DWA-N mobo and SC743TQ-865SQ case.
If you are thinking of a motherboard upgrade Intel just announce the next generation of "Nehalem" chips with the single processor i7 chip is going to be available on November 17th. I would wait at this time before configuring a new system. Do not have any idea when they will announce the two processor versions. The new 3.2 GHz Core i7-965 Extreme should leave the QX9770 in the dust.
But it will require a new motherboard. They finally are catching up to AMD in that this is the first chip with an on-board memory controller.
> Do not have any idea when they will announce the two processor versions.
Dual sockets have been reserved for the Xeon line in the past and I have not heard any rumors to indicate otherwise. IF, and I seriously doubt it, if they are capable of DP operation (none of the current non-Xeon's are DP enabled) it still is a long time off, at least 6 months. I do agree the Nehalem seems to be very capable and I also feel it is time to introduce a next-gen for the Harpertown, let's say the E55xx series, adding HT to an otherwise capable CPU, so one could get a 16-core system with HT. But that still is in the stars.
For Jarett it seems that an 8-core is still the better option than an 8-core HT Nehalem, since the gains of HT are on average around 20-30%, so a single Nehalem, even with HT, will still be less capable than a real 8-core Harpertown by a wide margin. In price/performance it may be different, but only benchmarks will show that and it is still too early to tell.
This is what I was thinking of getting. I'm still a little confused whether I should go with the dual quad or the i7 965 Extreme Edition? Doesn't the dual quad core have 8 cores while the i7 on have 4 cores but 8 threads? Where is this 8 core i7?

Your memory spec is incomplete you need FBDIMM's
I do not recommend RAID for your OS/Applications it is too difficult to try any sort of repair on a RAID array, many boot time tools will not work. I have a friend that had RAID 1 now twice fail on him and each time ended up rebuilding from scratch
I would suggest the WD VelociRaptor single drive on the motherboard controller for OS/Applications, it is the fastest SATA drive.
PCI-X controllers are not as fast as PCI-E
I also prefer Supermicro motherboards and cases plus SAS drives
>In price/performance it may be different
I think it definitely will be. Early benchmarks show a 30% to 40% speed increase in video rendering tasks for the Core i7 against a similarly spec'd Core 2.
If it were me, I'd wait a couple weeks.
Are you comparing the dual quad vs. the single i7?
I changed almost everything. Since I have some Raptors lying around I'll use those.

>Are you comparing the dual quad vs. the single i7?
The tests were run as equal as possible. A single Core 2 quad against a single Core i7 quad, both at the same clock speed.
thanks but i was comparing a dual quad (8 cores) vs a single quad i7. Right now it does look like they will make a dual quad i7 processor anytime soon.
The E5450 has a 1333 FSB, so DDR2-667 ECC FBDIMM is the correct memory type. DDR2-800 is needed for 1600 FSB, which is for the E5462 or E5472 CPU's. There is no harm in using DDR2-800 with a 1333 FSB, it will automatically throttle down to 667, but the price is somewhat higher than 667 memory.
Why opt for a triple redundant PS? Keep in mind that server cases are pretty loud. I suggest you have a look also at the 865 SQ PS as an alternative.
A raid5 requires at least 3 disks in the array. You can't have a raid5 with only 2 disks.
> Right now it does look like they will make a dual quad i7 processor anytime soon.
Where did you get that idea?
>i was comparing a dual quad (8 cores) vs a single quad i7
That's what I was talking about as well. The performance advantage of the i7 is such that the dual-processor Core 2 option may not be worth the extra price. It'll be faster, but not enough to be worth an extra grand.
Here is why I believe that dual-processor Nehalem's might not be to far off. At the July Computex show Intel showed off these two Nehalem motherboards. http://www.hexus.net/content/item.php?item=13654
Also earlier this year Sun leaked details on a 6-core version.
I just found this article on Supermicro at the August IDF show:
The Hexus pictures clearly show XEON sockets. Let's hope the Nehalem architecture will find its way into new Xeon's soon.
Good news, The W5580 and X5570 Xeon's, based on the Nehalem architecture will be introduced in Q1/2009, as well as lesser variants.
Look here: http://www.digitimes.com/news/a20081112PD218.html
what do you think will be the difference between the i7 Extreme and the Xeon W5580? I was going to go the i7 route.
i7 is single CPU only (albeit quad core), W5580 is dual CPU so with the same clock frequency (W5580 is 3.2) the performance difference is around 70%-75% with duals versus single.
And of course the price is generally about double, in addition to buying two CPU's the motherboard, memory, case and power supplies are all more expensive for dual processor systems. I did this last time go with the dual processors. But unless you are really in the video editing business big time, you might want to consider the obsolescence factor and spend less now on a single CPU system and save money for an earlier next generation replacement.
would anyone know if the W55xx series would need to go on a motherboard that only fits in EATX cases?
New mobo's are still in the making, so nothing is definite at the moment, but if history has the tendency to repeat itself, generally your statement is correct if we leave out custom sized mobo's for 1U chassis. It is to be expected that EATX will be the common mobo size for the 55xx series and thus require EATX capable cases.
