Yeah she definitely can't wait that long. By the time it gets announced, it probably won't be available for purchase until Black Friday.~October is the rumour for AMD's lineup, with GPU's around the same time.
I think you could build a pritty good system for close to the same price. The 2600 isnt really a great processor at ~200. The 3300x is arguably better. I built a pritty sweet setup with a 2060 KO, B450 & 3300x for 1500 with taxes & shipping just recently, and I splurged on things like PSU/mobo/Case & a 1TB SSD.
I haven't been able to price out a Ryzen build for under $900 centering around the Ryzen 5 3600 and decent mobo with 32GB RAM and stuff. Tried in May and failed. I'll try again tonight when I'm off work I guess. Problem is that the system would need a GPU and GPUs are expensive. No used parts either, unless it's this rig from my friend.
Or she buys Intel and uses the iGPU. I thought she said she games but apparently not.
