Standard Gaming Performance
We tested with a small group of games due to time constraints, but we picked games based on a variety of game engines to give a quick indication of the boards' performance. Additional testing will be done in our full board reviews but for this roundup we are using Serious Sam 2, Half Life 2: Lost Coast, F.E.A.R, Quake 4, and Battlefield 2. All boards were tested with the EVGA 7900GTX using NVIDIA 91.31 WHQL drivers. The Intel 975X boards were also tested with a single ATI X1900XTX card with the Catalyst 6.6 driver.
The two most performance oriented boards in our roundup are the ASUS P5W-DH and Gigabyte GA-965P-DQ6 boards, and they complete our gaming benchmarks with scores at or near the top of each game category. The most consistent board in the roundup is the Biostar TForce P965 Deluxe that stayed the course throughout testing by remaining in the middle sector of the group. Although the Biostar board did not finish first, it also did not have swings where it was at the top of one benchmark and near the bottom on another one. The ASRock board finished last among the 7900GTX boards four times and second to last on the Quake 4 test where it had its best showing. Overall, the scores generated by this group of boards are so close that you would be hard pressed to actually see or feel the difference in real game play.
The ATI X1900XTX cards finished significantly behind the NVIDIA cards in Half Life 2: Lost Coast where they generally score even or ahead of NVIDIA depending upon game settings. While their performance in the DOOM 3 engine games are normally several percentage points behind the NVIDIA based cards until recently, the difference in our Quake 4 test is also perplexing with the current 6.6 driver release. We ran our ATI X1900XTX in the ASUS P5N32-SLI board and the percentage differences between the GPUs were the same that we see on the AMD S939 or AM2 platforms. It appears to us at this time there is an ATI driver bug with the current Intel chipsets and Core 2 Duo, or perhaps a lack of optimization.

One thing that really bugs me about some of the MB manufactures is that some never state the exact number of PCIe lanes that are actually available on that second PCIe 16x slot. Some do some don’t. Some state it while in SLI/Crossfire mode but not when in non- SLI/Crossfire mode.Right now I’ve got an nForce 4 SLI board that has two PCIe 16x slots, but when in non-SLI mode they are at 16x and 2x respectively. When in SLI mode they are both at 8x respectively.
The problem with this is that (at least on this board) you cannot install anything but a video card in the second PCIe 16x slot when in SLI mode.
I’ve got an PCIe 8x SCSI raid card (LSI 320-2e) that I’m trying to use in the second PCIe slot at 8x, but this board won’t even acknowledge that its there while in SLI mode. And when running in non-SLI it only runs at 2x and becomes a bottleneck for this workstation.
So if its possible to provide some details as to what exactly a board can do on the second PCIe 16x slot in both normal and SLI/Crossfire mode, that would be most helpful!
For example on the ASUS P5W-DH Deluxe in your review it doesn’t state this information either way. But on the Intel 975XBX you do have that information.
So what does the second PCIe slot run at in non-Crossfire mode on the ASUS P5W-DH Deluxe?
Also do you happen to have a SCSI PCIe card you can test in the second slot (or any PCIe card for that matter) and see if the BIOS can recognize the card while in SLI/Crossfire mode? That too would be helpful for people who don’t care about multiple GPUs, but want to create large array workstations.
Thanks!
PS: nice article.

Excellent points! Constant change is here to stay :)On our ASUS P5WD2 Premium with i955X chipset,
we are now faced with that very same problem:
we don't need 2 video cards, because we do
mostly database development. And, we want
to dedicate the second "universal" x16 slot
to a high-performance PCI-E RAID controller.
(Santa Claus is going to bring me an x1900
PCI-E video card anyway, and that should
easily last me for another 20 years, min!)
Our consultant highly recommends the Areca model,
but it only performs best in x8 mode. On the
other hand, our ASUS User Manual states that
the second "universal" x16 slot can only run
in x4 mode, maximum.
That limitation was a single line of text
in that User Manual, but it is not mentioned
in any of the other specs for our motherboard.
His recommendation: switch to a server motherboard,
so we can use the Areca RAID 6 controller (not a bad
idea, actually).
So, I think we'll have to settle for the Promise
PCI-E model EX8350, which is also limited to x4 mode,
but it now supports RAID 6 too.
It only took about 4 hours of research to confirm
this limitation, however :)
Such specs should be better documented, for sure!
Sincerely yours,

I find it weird that the pcie card does not work in 8x mode. I see no reason why it wouldn't work...the sli pcb that you flip around only redirects the lanes AFAIK.vhx - Wednesday, July 19, 2006 - link
Too bad the motherboards cost more than a decent Conroe processor. Kind of sad to see the features lacking until you get into the $250 price ranges. You can spot an AMD AM2 motherboard with the same features for around $130ish, which makes this 975X chipset rediculously expensive compared to the newer AM2's. The TForce P965 looks like a great alternative for the price, although based on the 965P. Hmm upgrading to Conroe will be more expensive than I thought.... /sigh. What to do.Gary Key - Wednesday, July 19, 2006 - link
Wait, that is right, wait until the motherboard suppliers are in full production in August. There will be a large variety of motherboards available by the end of August that will make up the $50~$150 range with chipsets from the 945P to nF570SLI being sold. We will also start seeing the G965 boards in late August for those that want a mATX form factor, decent graphics,and the ability to upgrade later. If you need a board now, it will cost you. ;-)

Not to mention getting the Core 2 CPUs. :) I would expect prices to drop significantly within a month or so.

Jarred,Please say more about your comment on pricing.

I was waiting for the 965 as HDMI/HDCP-support is a must have for my new HTPC. Does 975 support this in the same way as the 965 ?araczynski - Wednesday, July 19, 2006 - link
great article!looking forward to additional mobo's appearing (and more importantly - prices dropping) beforei build my next rig.
i personally refuse to pay over $150 for ANY mobo, no matter the features. but i do realize that the initial price gouging is to milk the early adopters. i figure by early october prices should be just right for all the nice toys.

i know this is a dead horse, by why in the world can't these manufacturers make models that throw out some of these legacy 'extras' they keep putting on the boards?onboard sound, parallel ports, floppy connectors, etc...
