Conclusion - Very Fast On-board Graphics With HD Video Support
AMD's 780G is an improvement in every way over its predecessor, the 690G, offering better graphics performance, lower power consumption and greater functionality.
The 780G chipset will also facilitate smaller HTPC and multimedia systems. Since it obviates the need for a separate graphics card for HD playback, power consumption is reduced immensely, and cost can be kept low. Thanks to the integrated hardware acceleration for video, much less CPU power is required to play back HD-DVDs and Blu-ray discs. This, in turn, means less heat dissipation on the part of the CPU, enabling silent systems. The 780G chipset holds the new record for the lowest power consumption.
The integrated graphics solution, which is also the first dual-display capable representative of its kind, offers very good performance, and the new Hybrid CrossFire feature adds a noticeable performance boost.
Another look at the Gigabyte test sample
The GPU is surprisingly overclockable with all of the settings comfortably available in the BIOS, and performance improves tangibly when the integrated graphics core is overclocked. AMD has succeeded in improving every feature of the chipset, integrating new functionality and simultaneously lowering power consumption. We wish every company were capable of such feats.
Rival Intel is put to shame by AMD's chipset in every single one of these categories. And although Nvidia recently released a similar product with the GeForce 8200 mGPU, we have yet to receive a review sample.

I would like to know can i run a video card with this mother board,with all the high demand for great video quality in these new video games such as Crysis, BioShock, Jericho and many others that require a high end video card how am i suppose to play these games without oneReply
You just put in any PCI-E video card in the X-16 slot. With the appropriate processor and beefy enough video card, games are not a problem. The real beauty is that the onboard video is plenty for casual, older games at acceptable rates and also makes for a great low power HD media center computer.Reply
I do not get it, how come 2600XT is more faster than 3450 ? I thought 3450 is newer than 2600XT. Please explainReply
What about the northbridge overheating issue everyone is talking about? I've bought this board only to find out it has idle temps of 80C at the northbridge. I'm planning on buying an after market cooler to stabilize it.Reply
What revision is your board? I just received this board and it's the new revision 1.1 which has a bigger heatsink (you can see the pictures from the gigabyte site for both revisions 1.0 and 1.1). I am getting my CPU soon and want to also check the northbridge temperatures. What can I use to measure the temps?
I'm cooling my G780 on GA-MA78GM-S2H rev1.0 with additional pentium 3 box coller heatsink (fits perfectly) and radeon 3450 with p3 box fan :) - it works fineReply
Does anyone know if the radeon HD4850 works on this board with hybrid graphics and crossfire.Reply

Unfortunately, I'm using the rev 1.0 board. I fitted it with an HR05 heatsink from thermalright and its now just warm to the touch not hot. I'm using everest to monitor my temps. Aux now registers at 37 C, though I'm not really sure if its the NB temp. You can also use riva tuner among others.
I have a ASUS M3A78 EHM HDMI and I have a temperature of only 33ºc with my X2 BE-2350... I'm going tu put a HD3450, but i have a doubt... If i'm only in 2D graphics (like the desktop) the board switches to the HD3200? And when I need power does it "switch" to HD3450?Reply
I have a GA780...DS3H rev1.0 (ATX) and the northbridge heatsink is large but made of some cheap light zinc alloy - waste of time IMHO, 70+ degrees and memory errors - but only when using a PCIex16 graphics card. The problem eased when I added a 40mm fan on top of the rubbish heatsink. I wrote to gigabyte about the issue, who said - tampering with the heatsink invalidates your warranty. Sounds like they're burying their head in the sand over the issue. According to some posts on SPCR, and here, the thermaltake HR05 replacement fits.Reply
I would question the QA process of a mobo manufacturer who offers not only a poor heatsink design, but a 4 phase mosfet unable to cope with the TDP of some of the higher power phenoms (see Tomshardware and Anandtech). The 780 board by XFX has a heatpipe solution on the mosfets and northbridge which looks like a better design, and similar price (cheaper if you count having to replace the deficient heatsink by Gigabyte). The Asus M3A78 possibly has a better heatsink on the northbridge.
