After consideration, I've decided to stay with Intel for my CPU upgrade. Best Buy has a i7-1700K on sale for $344...more money for the chip but higher frequency on base & boost ends. The new mobo I'm using is a Gigabyte Z490 Vision G. A Noctua NHu12S fan cooler and 2x16 Ripjaw DDR4 3200 CL16 ram sticks complete the rebuild.
Is it required or advisable to do a clean install of Win10? If so, it may be a problem as I upgraded from W7 a couple years ago and have since lost the W7 product key. If the answer to the former question is yes, it it drivers that require the reinstall? Any way around that? I'm $140 over budget now and would be bummed to have to buy another copy of Win10.
TIA
