its a lot easier to upgrade storage than to upgrade your processor and graphic cardYou're spending a huge % amount to improve render times, yet have only 1Tb of storage for other stuff. If you are doing a lot of HD Video( or 4K by proxy perhaps?) then you will need much more storage very soon . . . and IMHO it would be better to include it at the start.
3Tb drives are reasonably priced and this will ensure yr BIOS overcomes the 2Tb limit.
Hope that helps.
I've tested it out and opencl rendering (basically AMD rendering works great) and their divers are actually better than nvidias. That being said I am using an nvidia card because I got a really good deal on one. But given the option to trade for equivalent amd card I would do it in a heartbeat.That's why I recommended more storage and a lower card. Its ok to upgrade later but 1.2TB is a lower limit for a standard machine these days rather than a video editing one.
I do some video editing and I have some intermediary files in the 100GB range for 40 mins of video so you don't want to run out.
If you have a budget you need to not upgrade in the next month...
Also I would still stick with Nvidia if you are using Premier Pro, although support is much better now for AMD its still newer and the Nvidia drivers can be more stable.
