Does it support Gigabyte R9 290X GDDR5-4GB crossfire

On the Asus compatibility list (at http://www.asus.com/Motherboards/Z97A/HelpDesk_QVL/) it shows only one "official" Gigabyte video card: GV-N670C-2GD (BIOS: V80.04.19.00.2E) This does not mean it won't work.. They typically try to push ASUS branded cards and it would be impossible to test every card on the market. The board does support 3 simultaneous monitors off it's 4 stock video connectors (VGA, DVI-D, HDMI and Display Port) and the board comes with a NVIDIA branded SLI cable (ASUS P/N: 14010-00130600). I would call Gigabyte and ask. Great motherboard.. Make sure to update the BIOS. If you are planning on running Windows Server 2008/2012 the network card has major driver issues and for other drivers such as SATA/RAID you will need to use manufactures drivers (INTEL).. Otherwise download the NEW drivers from ASUS for Windows 7/8/8.1 and it should go smoothly (Drivers on DVD are older and have bugs supporting booting from RAID arrays). The board also consumes very little power and supports SSD's. - Hope this helps.

Laura is correct. Radeon R9 290/290X use a new processor codenamed "Hawaii". You can crossfire 290 + 290x, etc. Radeon HD7970/7950 use the previous gen processor named "Tahiti". AMD rebadged the HD7970 to create the R9 280X so a 280X can be crossfired with an HD7970/7950 (3GB or 6Gb are ok).

In short, yes it supports g-sync. Any 650ti or higher card will, but only with display-port.

Yes it should work with this motherboard, to be sure check gigabyte website find the board page and look at compatible memory modules supported by this board to be sure

I don't know about that card specifically but I can tell you I have a Sapphire Radeon R9 290 installed in mine and its huge!!

It has a Radeon R7 Built in. So you don't need a separate gpu. My understanding is that it also supports crossfire with other Radeons.

From the Gigabyte website: Multi-display support with AMD CrossFire Flexible graphics capabilities - Up to 2 VGA cards are supported for 2 way AMD CrossFire (running at x16, x4 bandwidth), delivering the ultimate in graphics performance for gaming enthusiasts who demand the highest frame rates without compromising on resolution.

I'm not sure an r9 290x has the horsepower to drive that many monitors. A 2k monitor takes about 1.5 to 2 gigs of VRAM to drive, and the reference 290x has only 4 gigs. Without sufficient VRAM the regular ddr3 ram is utilized which is much slower than GDDR5. And no crossfiring 2 cards doesn't double the effective amount of VRAM, only the computational workload is shared between GPUs, the second cards VRAM isn't utilized in crossfire for display driving. I would look at non-reference cards and see if one is made that can support your needs.

It's only partially supported. The R3 chipset and GPU can utilize up to 90w of power. This unit will work, but you'll find yourself with limited power.

Yes Aidn, Of Course. This board will support nVIDIA as well as AMD Discrete GPUs.

Yes it will, but dang, you're gonna need a big PSU :P. I think my 900Watt won't even power a second 290X GPU lol. If you want a new GPU, this is the one to get. ATLEAST 200Fps Every game. Cod ghost, perfect to play with , besides because there is optimization problems in the game, I get a 0.2 second lag every 10 mins lol. No bad, xD.

It should accommodate that card fine although you may have to remove one of the drive cages to accommodate, there's a secondary mount for crossfire/SLI cards. I'd be more concerned about where the radiators go. Google and see if anyone else has this install.

Yes sir. I am currently running 2 x AMD 7870's on it very nicely. The second PCI-E rail is even at 16x so should work fine with any crossfire set up.

750 Watt should be plenty!!! You may have a bad power supply and it may need to be replaced that happened to be before. I have an tx 850 corsair power supply and I run 2 of the r9 290x crossfire, 2 ssd, 3 hard drives, i5 2500k oc 4.7 ghz, sound card and a ton of other stuff. Hope this helps

According to the compatibility list it is supported. Here is the link for you to verify, just in case. http://www.evga.com/Products/Product.aspx?pn=100-BP-2770-B9

Yes, It does....Check this list if you want: http://www.geforce.com/hardware/technology/physx/supported-gpus

I am sorry I do not know the answer to your question. I will say I am liking this card and will end up getting another one to crossfire. Good luck.
