Hi, I got a new qnix 1440p monitor but my new graphics card hasn't arrived.

I always assumed most of the heavy work done by the graphics card was real time lighting / physics / other calculations and that pre rendered videos shouldn't pose as much of a problem for a radeon 7790.

Was this assumption wrong and that the radeon 7790 is supposed to struggle with pre rendered 1440p, or could the problem be with the monitor / driver?

Actually, your video watching experience, as Avro stated, isn't really determined by your GPU. It's determined by your internet bandwidth, however it's also mostly determined by your processor. Your CPU actually has a far bigger role in video playback than your GPU does surprisingly enough. If you did as Avro suggested and you're still experiencing bad stuttering, what CPU do you have?

UPDATE: I have a 2 core, AMD A4-3305m APU with an HD 6480G integrated graphics card. While both the GPU and CPU are crap, it's worth noting that I have somewhat infrequent but noticeable stuttering at 720p sometimes with internet videos depending on the video player, and major stuttering with any videos at 1080p regardless of locality or player...

You're actually looking at this the wrong way. Even an old Radeon HD 5450 could handle that resolution perfectly with pre-rendered 2D video. The problem here is most likely that your internet isn't fast enough to receive that amount of data without stuttering. Try letting the video spool up and then watch it. I'd be willing to bet that the stutter no longer happens. Also, make sure that your internet cache is clear because that can also cause HTML5 video to stutter. Here's the test you should perform. First, clear your cache and restart your browser. Then go to the YouTube vid you want to watch, get it started and pause it. Let the progress bar at the bottom reach halfway and then start watching it. The stutter should be completely gone.

However, on my previous computer which I believe had a somewhat decent 2 core Intel CPU which would probably rank higher than my current CPU, I also had a really terrible graphics card (somehow even worse than my current one) being an Intel HD GPU (the ones that are so bad that Intel literally doesn't bother giving them a numerical value). However, on that previous machine I could swear that I remember 720p video playback being much smoother, and that I watched my fair share of 1080p videos, iirc.

Sorry, I forgot to mention to that I did actually buffer the video before watching and that the music wasn't broken.
Cpu is currently intel dual core e5200, so i guess thats almost definitely it? though I don't really have anyway to 100% confirm it before my parts arrive do i?

Ding-ding-ding-ding!

It's a duo core core processor that's over 5 years old, and when it was released it was a budget processor selling at only $80. There's no way it was ever meant for 1440p video playback. If you're replacing your current CPU, then I'm sure you'll probably see a huge difference in performance for video playback.
