I'm looking to upgrade my video card so I can functionally do some video editing. Have a bunch of 4k clips, although I can use the "optimized media" in davinci resolve. Right now I only have a GT 620 which I think has 1gb (shared?) gpu memory. I've got an i7-3770, SSD drive and 24GB of RAM (DDR3 I think?).
I have to imagine virtually any modern graphics card would be a nice upgrade, I don't think I can go for a top-of-the-line as I'm more or less just starting off, but don't want something that will hold me back or continue to cause slowdown frustration either... I guess I'm looking for the best value/best balance?
If 4k matters, the extra GPU memory makes a big difference to real time performance. The other ting to consider is Resolve 14 has a new playback engine which gives much better performance so maybe you can get the required performance with the new version. It's still beta so I'm not recommending upgrading to it yet unless you are prepared to beta test.
