I bought a XFX Radeon R7 240 card, as on the AMD specification page, they say this card 4k support.

I have a 4k monitor (3840 x 2160 @30Hz). I used this for office work and light programming. I am heavy user, as I have lots of applications open. I wanted a big screen as I need to open a number of windows at the same time and need to compare and cross reference information. 

I don't do PC gaming (except for very old games or Flight Sim). 

The Radeon R7 240 was great for 4k work. I had a TV card and it could cope with this.

However, the card (or PC) seemed to struggled with 4K sample videos from YouTube. I know it is not due to the internet, as I downloaded a few samples. 

Question: Is right that AMD market the R7 240 as a 4k product ((3840 x 2160)  given that it struggles with 4k YouTube videos?

Question: Does having more memory make any difference on a graphics card, if you are a 4k user e.g. 1Gb versus 2Gb? Or is memory useful to gamers?

Question: Many of the graphics card seem to aimed at PC gamers, but which graphics cards are best for 4k monitor?.

That card is rather underpowered for 4K 

You should be using an R9 card which is more powerful and better suited.

The R9 is a very expensive card and beyond my budget :-(

 

I tried a MSI Radeon HD 5450 card with my 4k monitor and I can run it at 3840 x 2160 (via HDMI). Even though the spec says HDMI is limited to 1920 x 1080 (it picked it when I did auto-detect on CCC) :-)

I don't understand why I see negligible performance differences between my Radeon HD 5450 1GB (64bit) and the  Radeon R7 270 2GB (128bit).

Looking at the specification -  the R7 240 should have outclassed the HD5450 in every way.

Both cards struggled with 4k YouTube videos. They both dropped similar number of frames etc.. 

So I wonder, what is the benefit of a faster more expensive graphics card? Are all the benefits for gamers rather then 4k users?

Anything can be 4k supported, By doing so it allows 4k content, doesnt mean it will be fantastic for gaming, but 4k movies ect. can be wonderful for playback.
