It's rather close to Zen 2 at this point, you would expect discounts on the Zen+ chips to get better and better. I built a machine recently for someone and opted for a discount 2600. Could budget for a better cooler then and slightly better memory for the cost of the 2600X. Then overclocked it to match the 2600X.
My thinking was that spending a lot on any of these chips was a mistake with Zen 2 so close, I would prefer the budget on a better cooler and memory because they will still be in the machine in a year. Then if needed, I could in 18 months just drop in a Zen 2 eight or twelve core perhaps. Get a core, clock and IPC upgrade.
Very impressed with the 2600, I didn't spend forever fine tuning the last percentage. Bunged it to 4GHz, kept the voltage modest. Ran happily along at ~60 degrees stress load and brings a lot more muscle to a person who was using a 4th gen i5.
