Do i have enough Computer for a jump to 4k?

I have a mac 3.1 8core 2.8ghz 24gb ram and a 1gb video card. basically I want to know if this is enough machine to make the switch without noticing much of a difference in work flow and speed?
Thanks

You should grab some 4K camera footage and try editing it yourself. If you dig around you can find camera footage for lots of different 4K cameras.

I've got a 3.3ghz i7, with 8 Gigs of ram, and a 1 gb video card and I can run 4K Video pretty seamlessly. It gets a little chunky when I'm working with a big library of video, or have a lot of effects applied. But it's doable.

It depends on the bitrate of the video. Internal GH4 4k footage is only 100 mbps, which is not that bad; there's a lower amount of data to process than even 1080p on some cameras, certainly any raw format. But 4k raw video files from a Blackmagic Production Camera, for instance, are enormous. There's far more data to be processed there.

Guy's suggestion is good; if you can find some 4k footage of the variety (format and camera) you have in mind, it'd be worth trying.

I don't know that much about computers, but the people that helped me do.

What I understand is that, if you want a good computer to work on video (on a budget), you should go for processing power instead of graphics card. For a professional graphics card you would have to spend a couple of thousand euro/dollars, but for a very good processor, like mine for instance, a six core i7 that set me back 500€.

If you are on a mac, you cant really change things much. I understand some macs have AMD graphics cards, or maybe i'm saying something terribly stupid, but if that is the case, I think those dont have CUDA cores which are important for video editing.

I had a 27 inch iMac, top of the line in 2013. It was decent, for a short while, for a more heavy workload it wasn't enough so I got a decent PC instead. Don't want to start a mac vs PC discussion here btw

But to put things in perspective regarding the CPU vs GPU, my computer engineer friends made video editing workstations for a company with no graphics cards in it. How they work? dont know, but it is something to search online and learn more about if you consider building a new computer on a budget.

Before you invest in a new system, try to improve storage speed FIRST by either using SSD drive or raid two standard drives. I edit 4K material (Also 1080 200Mb prores) on imac core i7 3.4Ghz, mid 2011 20Gb Ram. When adding a 500G SSD I got the performance i needed.
An SSD gives about 500Mb/s, 2 Raid drives gives about 3-400Mb/s, both sufficient for 4K editing. External SSD gives the same class of performance if you have USB3.
