Just replaced my 5800K+5770 (long story..) for around R9500 for nice a 2400G build. Decided in the to splurge a little on the board, storage and memory
new:
2400G OC 3.9Ghz core 1.325v , 1525mhz igp 1.225v (2200g can do similar speed with comaparable performance, but less guarantee and more volts)
Cooler Master H411LR (probably not that much better than stock, but I need the rear flow in my tight case)
MSI B450M Mortar (the real star here)
G.Skill Ripjaws F4-3200C16D-16GVGB (not QVL, but XMP2 stable.. phew..)
Mushkin Pilot 500GB NVME (for R1650, it was hard to pass up)
Salvage:
1TB HDD (SG, I think)
Lian Li PC-A04B with 2x120mm in, 120+80mm out. (small, unassuming, and quiet)
Corsair CX 430W (still has legs)
I probably could've gone with a GPU build, but I didn't see any good value below RX570, and I don't put 150W extra on my PSU. Nonetheless, I have a good upgrade path down the line, and I can play Skyrim @1080p (better than the 5770 did!), record/stream Celeste runs, and do work when needed.
