for two r9 270 GPU crossfire is enought?

This unit will handle almost anything to be sure about your configuration try tomshardware.com/powersupply it is what i used to configure my pc.

theoretically, it should but the general rule of thumb with Crossfire and SLi is to have two (or more) cards from the same manufacture and same cores, etc. if it works, you might not get the most out of the pairing and you'll only see the smallest amount of dram because of the 1Gb card. personally, I would look for another XFX HD6670 and pair those two. hope this helps.

It does support crossfire and i think it supports 3 monitors maybe more sorry couldn't be more helpful!

I would have to say no.From the AMD website: "AMD CrossFire™ harnesses the power of two or more discrete graphics cards working in parallel to dramatically improve gaming performance."This board has only one PCIx16 slot so it should only be running one discreet card. Though I'm personally using the onboard video from an A series chip.

I'm using a Gigabyte Z97X-UD3H-BK - fits fine. From the looks of the 2 R9 270 GPU crossfire I see no problem. You will have room to spare.

There aren't any - its all handled over the pci-e lanes and software. Therefore, you don't need any crossfire cables or connectors when running 2+ cards.

sorry to tell you but you can't crossfire these because they are low profile and don't have the bridge connection. I got them for dual GPU with the 7660D in the A10 cpu.

Two of them is roughly the same amount of shaders as a 7970 or r9 280x but has less memory and less memory bandwidth. If you can get a second one for less than 250 it's worth it to crossfire in my opinion

Yes - I'm actually using an R9 270X with it right now. That range of card ($150-$250) is a great fit for the APU processors for a balanced system - any cards more expensive than that and you start to find that the rest of the platform is holding you back (depending on the game of course).

Yes 1250 watts is more than sufficient to power both cards. They both turned on for me with a 1000 watt PSU.keep in mind that these cards require two eight pin PCI-X connectors. Not the standard six pin. To crossfire two cards you will need four separate eight pin connectors.

Depends on your APU if yo want to go cross fire you need to check with your APU it will tell you what to use fir cross fire, but if you want to go with a single GPU I think anything will do I would suggest the 980 series if you got the $$$

Yeah, I have the same mo-bo and I installed two GTX 780's on it, so you'll be fine installing two GTX 660ti's

I have no personal experience. I suppose it would depend on how many GPUs you are planning on using -- I suspect no problem with two. More might be pushing it. So far I like the case.

yes,the 7770 is compatible and you can check this websita for more information http://www.techpowerup.com/reviews/HIS/HD_7750_7770_CrossFire/

Yes. With the mobo you can actually use upto two pci-e cards like this in crossfire.

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.

No, first of all CrossFire is AMD only. SLI only works for the same cards and only if they have the same memory.
