I have just bought an ASUS PQ321Q 31.5" 4K UHD monitor. (I like big screens

)

I would like your advice about a suitable graphics card - to be used for video and graphics editing only - no gaming

requirements:

must drive a 4K UHD monitor at 60fps
single card
preferably small form factor
as quiet as possible
not ridiculously expensive

candidates:

ASUS GTX960-MOC-2GD5 GEFORCE GTX960 OC 2GB $350

ASUS GTX970-DCMOC-4GD5 GEFORCE GTX970 OC 4GB $600

Both cards have:

DVI (DVI-D and DVI-I)
HDMI (HDMI 2.0)
Display Port
HDCP Support

If either of these would be suitable, is there any point in buying the more expensive card?

Hi Sideface, if you are looking at video editing consider capture/playback cards designed for video. The consumer graphics cards and drivers can have issues when it comes to video.

Also if you want to get into 4k type stuff, it is in a state of transition flux where the standards are a moving target. This is mainly because the "standards" wish list is greater than the achievable with technology at the moment. For example I note the HDMI ports on your monitor are 1.4 spec, which might limit your input video levels and standard to Rec709 but support higher resolution of feasible 3840*2160.

For graphics, you are dealing with sRGB standard despite colour spaces and feasible monitor range being greater.

Anywhoo, just consider what you are trying to achieve

ET: "Maybe; you have some freewill, but you chose your path by arrangement"

Me "That sounds like a program with no freewill?"

ET: "We will catch up when you end this cycle"

Me: "Sounds like a 'KPI'!"

ET: "Did you read the terms and conditions?"

Me: .....

Displayport can drive 4K60 fine, you could even get a 750ti as the very minimum as it can drive 4K60 too.

I would buy the 970 for piece of mind because it has 4GB vram, which will allow you headroom to playback 4K footage using GPU in Premiere Pro

Ideally you'd have a Quadro but they cost so much more...

So long as you choose a card that has DisplayPort it's fine.

Just to hijack on this a little bit, has anyone dealt with dual 4k monitors on a single pc without issue?
I've got a pc running 2 viewsonic vx2880ml's attached to a firepro w4100 which should be capable of driving the two and it consistently breaks the eyefinity span and has trouble coming back from sleep.
It will work fine for a day or two and then need to be completely reconfigured as it thinks both screens should be mirrored and pumping out 640x480.

The new 4k monitor is everything I had hoped for (pity about the price).

I've ordered the ASUS GTX970-DCMOC-4GD5 GEFORCE GTX970 OC 4GB

Yea I'd love that Dell 31.5" 4k display!! but it would mean upgrading to a workstation machine over my Dell XPS laptop.

My 2408WFP is getting long in the tooth and is starting to lose colour gamut as the CFFL back light drifts warmer and warmer...still 97% of Adobe RGB though after 6.5 years

Hard to resist the thought of a new PC and new display when thinking about the performance and resolution benefits.

Easier to resist when we're talking spending $6-7K in total on a new machine and display!!!

Make sure to use the Displayport connection.
