High-Resolution Gaming Performance
We are using the same game benchmarks in our standard gaming performance section that consists of 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 SLI results on the ASUS P5N32-SLI SE utilized two EVGA 7900GTX cards and the 91.31 drivers with profiles enabled for each game. The CrossFire results on the Intel 975X boards utilized our ATI X1900XTX and X1900 CrossFire Edition cards with the 6.6 Catalyst driver.
The single card 1600x1200 results with the EVGA 7900GTX card shows the ASUS P5N32-SLI SE taking a clean sweep of the benchmarks. The performance of the 7900GTX and nForce4 Intel Edition chipset made a small but measurable difference at the higher resolutions as the boards started to become GPU bound. Due to the strength of the NVIDIA SLI setup along with obvious ATI issues in the Half Life 2: Lost Coast and Quake 4 benchmarks this same board sweeps our multi-GPU tests.
However, we also noticed where the ATI cards made a very strong showing in our standard benchmarks in F.E.A.R. and Serious Sam 2 by finishing first, they fell behind the SLI setup when running CrossFire indicating a lack of optimizations or possible driver issues in our tests. The performance percentage drop of the ASRock board compared to the other boards when moving to 1600x1200 was even greater than at 1280x1024 indicating that X4 PCIe operation is certainly hampering its performance.

Thank you for the comments. Our focus on the first cooler roundup will be on units that cost under $25 but the Tuniq will be included as a reference point along with the retail Intel unit. Our follow up will include the high end air coolers and some water cooling units.The Tuniq is considered to be one of the best air coolers available at this time although we are starting to see this design being incorporated by other suppliers quickly.

Hope you can get an Arctic Cooler Pro 7 into that cooler review. Quiet as a tomb and mighty cool.jonmcguffin - Thursday, July 20, 2006 - link
A feature built into the Core 2 Duo processors is this new Digital Thermal Sensor that supposedly has the ability to provide much quicker and more accurate thermal information about each processor. The key with this though is that it requires support from the motherboard. Why did you guys not mention this feature in any of the motherboards you tested?My guess is that since the P965 was "built" for Core 2 Duo, my guess would be that it supports this feature while the older 975 does not. In going back and forth between pro's and con's of the P965, if this feature is in fact built into the chipset/motherboard, it is worth pointing out. I'm not really an overclocker though I do want to buy a system that will be rock solid in stability for many years to come. Quite PC's that are very reliable and stable are critical and this is a good feature.
Also, you reviewed the Abit AB9 Pro motherboard a few weeks back but somehow it was left out of this overview. At $160 on the street, despite it's layout issue's, this looks to me like perhaps the best board right now for the guy who isn't rich and just wants a very solid Core 2 Duo mobo.
Hope you get a chance to review and respond.

Jon,The Gigabyte DQ6 actually has the ability to select readings from either sensor (Digital/Legacy) on the CPU in the power management settings. We will go over this in detail in our full review of the board or other Conroe capable boards in the future. These type of features along with audio and storage performance are not generally not reviewed in the guide articles but covered in the full product reviews.
The Abit AB9-Pro is shaping up to be a very good mid-range board (prices around $142 already) once the bios is complete. We are due to receive bios B6 next week that is optimized for Conroe and allows full memory configuration from both a timing and ratio viewpoint. The board was not ready to be included in the buyers guide until Abit had a final bios to us. We will report the results as soon as we complete testing.

We had planned to include the Abit AB9 in our roundup IF Abit got the memory issue fixed before the review. Unfortunately even the latest beta BIOS we received on Tuesday does not fix the issue. There is no means on the current Abit board to change memory speed or timings. It supposedly reads the SPD and boots at DDR2-533 5-5-5-15 with every dimm we tried. You can't run Value Ram at DDR2-800 for example or run DDR2-800 at rated speed. Or change timings to 3-2-3 at DDR-533 even if you know the ram can run at those timings. We did not think it fair to make a big deal of this in a review since Abit is supposedly working on it, but we see they are now also selling the board at some retailers and memory is still broken as far as we know.We consider this problem, if not fixed, to disqualify the Abit from consideration by any Enthusiast. We plan to do a full review of the Abit AB9 Pro if and when Abit fixes this major problem.

Jon,Why would more accurate thermal sensors
have high priority, if the Conroe runs
much cooler and more efficiently?
Are you planning extreme O/C, perhaps?
Wouldn't a superior HSF have higher priority?

Just curious here.

The usual best from Anandtech..I was in a bit of fog if switching to conroe or not, but now I have a mutch more clearer picture. After the part2 of this suite, it will all be clear to me.P.S. Your articles on Nvidia's NForce 4 platform made me choose that platform and AMD64.
My sincere thanks, I owe you a lot

Thanks for putting this article together. Your effort has not gone unnoticed.Howard - Wednesday, July 19, 2006 - link
Anybody know what chips it uses? The 5-5-5-15 DDR2-667 variety, that is.Gary Key - Wednesday, July 19, 2006 - link
We still have additional memory selections from a variety of suppliers arriving for further memory reviews at this time.
