Best value CPU to replace an Ivybridge Intel Core i7-3770K 3.50GHz?

[At The Gates]

Hi guys

My Ivybridge setup is getting pretty long in the tooth and the motherboard is starting to playing up with wonky USB connections. I have £500 to replace the CPU, motherboard and ram, can maybe go a bit more if there is something worth it. This is setup for pure imaging work. Photoshop with large raw files and scanning medium format TIFF and working on those. No gaming. I plan on just keeping my R9 270 and Samsung 840 Pro SSD unless i can squeeze a small NVME drive into the budget.

I am pretty out of the loop on CPUs. With my budget even Coffee Lake seems to expensive, are there decent AMD equivalents these days in my kind of budget?

Thanks
