AMD's New 780G Chipset Has Powerful GPU

Output: Dual-Monitor, HDMI, Up To 4 Monitors

AMD's 780G and 780V chipsets are the first on-board graphics solutions to offer dual-monitor support. If the 780G/V board is equipped with a DVI or HDMI connector in addition to the conventional VGA output, the board can drive two displays.

An HDMI-to-DVI adapter cable.

If the only digital output present on the board is an HDMI interface, you can still use your TFT via an adapter or an HDMI-DVI converter cable. This will not have any impact on the HDCP copy protection used on HD-DVDs or Blu-ray discs.

Gigabyte also equips its board with a DVI connector

The Gigabyte board came equipped with a DVI output as well as an HDMI connector. Since these two outputs use the same source, connecting two digital displays is not possible.

Choosing between HDMI and DVI in the BIOS

When equipped with a hybrid-enabled ATI graphics card, the system can drive up to four monitors, with the add-in card providing connectivity for the additional two displays. Depending on the manufacturer, a typical add-in card will either sport two DVI ports or one DVI and one VGA connector.

ATI's HD3450 features both a VGA and a DVI connector

    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 one

  • 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.

    I do not get it, how come 2600XT is more faster than 3450 ? I thought 3450 is newer than 2600XT. Please explain

    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.

    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?

    Thanks

  • 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 fine

  • Does anyone know if the radeon HD4850 works on this board with hybrid graphics and crossfire.

    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?

    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.

    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.
