Games play slower after PC hardware upgrades

[spichersam]

I recently upgraded my PC hardware yet now my games seem to be more fidgety and less responsive! Any ideas why this could be happening? I updated my BIOS.

Specs before upgrades:

Windows 10 Home
Intel Core i7 4790
GTX 1060 3gb
Generic DELL motherboard from DELL XPS 8700

Specs after upgrades:

Windows 10 Home
Intel Core i5 8600k, 6 Cores, 6 Logical Processors
GTX 1060 3gb
Asus TUF Z370 Pro Gaming

Clean install of windows?

Doing a full reinstall on a pre-built Dell with obviously OEM Win10 can be tricky....

You might have better luck w/ deleting assorted chipset/GPU references from device manager, and hoping WIndows detects the new hardware, and then correctly install new drivers in place of old ones...
