Think these will go alright as mid tier and entry level CPU/GPU combos. They are offered at this very low price point as a base spec with room to upgrade most components.
Spec: Ryzen 5 3600 | GTX 1660 Ti 6GB (MSI Ventus guaranteed for first 35 orders) | 8GB 2400MHz | 240GB 2.5" SSD | Biostar A320M MB | 550W PSU | Leaper Small Case
Price: $799 after R53600-1660Ti
Spec: Intel Core i5 9400F | RX 570 4GB | 8GB 2400MHz | 120GB 2.5" SSD | Biostar H310M MB | 550W PSU | Leaper Small Case
Price: $599 after i59400F-RX570
Community-recommended upgrades for these from previous deals are the B350/B360 motherboard ($39) and 240GB NVMe SSD drive ($59 from 120GB/$39 from 240GB, requires B350/B360 motherboard for m.2 functionality), and/or 16GB RAM, either at 2400MHz ($99) or 3200MHz ($119). Both RAM upgrades are a little dearer at the moment due to supply shortage and price fluctuations.
I've contacted numerous customers regarding existing orders, and those that are due should be shipping by week's end, applying to low-end and high-end systems (570/580/1660/5700/2080 systems) but feel free to reach out for specifics if you need to.
