It depends on the file size, your apps and how much time you need to save over what you're doing now.
Be$t bang for the buck is a sliding ratio. For some, the iMac Pro is the only real choice. Apple has an inventory glut right now which means there are many choices in the Refurb Store right now—Apple's way of lowering the price without "officially" lowering the price. This i the Mac made for graphics and AV pros (till the Mac Pro ships in September, at least).

That $4,249 base model iMP will be a big step up from what you are using now.
You want an SSD as graphics files involve writing to disk. The tiny SSDs in the Fusion drives off-load these tasks to the HDD and that can't be helped. The 3TB Fusion has a larger SSD but still...
When Time saved=Money earned, the true bargain is rarely the least expensive option.

I just read some reviews on the base 2019 iMac that one photorapher complained that its much slower than is 2014 MBP..
thats what I have.. I have a 2.5 ghz For I7 with 16gig of ram ddr3
Without context, no one here will know but that can easily be possible. If it is the base model with a fusion drive or an SSD that is too small, not hard to believe at all.
[doublepost=1561151406][/doublepost]If you have never replaced the SSD in your 2014 MBP, you can give it a nice performance boost for $150(1TB) – $250(2TB) including tools and a new keyboard cable. If the battery is getting too old, this is the time to do that, too.
The original SSD is a very slow (relatively speaking) AHCI blade. Because of the PCIe 2 bus, a fast NVMe 3 x4 blade like the Aura X2 Pro or 970 EVO ($500) is a waste of money in these. A slow NVMe 3 x4 blade costs a lot le$$ and still runs 2–3x faster. The Crucial P1 ($127 1TB) and Intel 660p ($228 2TB) are the ones to look at since they're still faster than the bus.
The keyboard cable in these is quite fragile and can be disturbed just by removing the back which makes it go bad. It has to be removed when replacing the battery anyway. Fortunately it's $9 on Amazon.
