    Very informative article. Nice to see there are motherboards with different features for different users/tasks.

    Great article, I think this shows pretty conclusively that there is no benefit to upgrading to an AM3 based system. If you already have an AM2+ system, you can easily just drop in a new CPU and you system will be every bit as good as a brand new system with DDR3. You just need to make sure your motherboard supports the power requirements of whatever you want to drop in.

    Hooray AMD for having cheap solutions in these hard-economic times!

    Boo @ Intel! i like the product, but my wallet & Girl do not like the cost!

    Well bpdski there is no point upgrading if you're AM2, but if you're building a new PC AM3 is the way to go in terms of your computers longevity. Very informative article.

    thanks alot for the info , my first choice was allways asus , but now i now what i need when im going to unlock core , and now i saw the benefits of sideport memory .

    We were successful in achieving a 900 MHz stable overclock with the integrated graphics chipset by setting the BIOS to increase northbridge voltage by +.210mV.

    Well, .210 mV = 210 microvolt. I don't think it would make much of a change. Maybe it is 210 mV or, .210 V. :)

    "Now we're seeing another benefit for the AM2+/DDR2 boards: both the Foxconn Cinema Premium and Biostar TA785GE 128M are drawing less power than their AM3/DDR3 counterparts."

    How comes? Didn't we all agree a long time ago that ddr3 supposed to be more energy efficient out of the two? (Lower voltage and stuff?)

    Great article, this will help a lot of people to make their AMD budget motherboard choice easier, thank you Don.

    Ah nice line up and a good review. AMD has a better platform when factoring in cost and durability compared to Intel war I end up replacing the board after a few months to a year once the cpu power stage begins to degrade. Then there is performance on the I/O end and stable and steady stream to the cpu that is unaffected by other devices compared to FSB but on the cpu end need to be improved and same for INTEL.

    before reading the article ... THANK GOD errr... TOM's ... I have been waiting for a 785G mobo test since release ... all I got was crap load of P55 ...

    so after reading the article, nice work. I have the cheaper MSI 785GM-E51 in my build atm, but the E65 looks very solid and worth the cost.

    Does the Asus M4A785TD-V EVO have x8/x8 support or x16/x4? on newegg it says x16/x4

    Early adopters of usb 3.0 may wish to note that cards will probably be pcie x 4 (to cope with the bandwidth). Those extra slots may be good even w/o a neeed for crossfire.

    "The irony is that Foxconn chose Realtek's ALC888 codec to drive the Cinema Premium instead of the ALC889, which has a better signal-to-noise ratio and can be found in the Gigabyte and MSI 785G boards in this roundup."

    Actually, it makes perfect sense to use a subpar codec when the intention of the board is to use digital audio which will never touch the Realtek codec. When you use analog outputs, the benefits of DD live and DTS connect are worthless because whatever audio format the content is in will be decoded in surround sound and output over the analog outputs.

    DD Live and DTS connect are simply transcoding AAC or game surround sound into Dolby Digital or DTS surround sound where it is passed as DD or DTS over the spdif or HDMI port, never touching the realtek codec making it's quality a non-issue. The purpose of the board is digital connections only and the codec was simply added because all boards need one.

    DD Live and DTS connect are simply transcoding schemes for PC digital audio into a format that receivers can understand. If you think of it that way it is easy.

    +1 to Kohlhagen's question. It does state that the board is x16/x4 on Ausu's website, though...

    Just bought the ECS board from newegg... it's $70 (after rebate) right now.
