By oomph I can only assume 3 things.
Shitty Power Supply
Old mobo with less than an X16 for the PCI-e 3 lanes
Low RAM?
Never skimp on a PSU, Those things can last you decades and go through multiple whole PC changes, something between 700 watts and 1000 watts should keep you good for the next decade of cards even if you SLI them. If you want trusted information on them

My opinion is just go Seasonic, they actually make their PSUs, other companies mainly rebadge the Seasonic and other OEM ones under their names.
Old mobo(motherboard), easily the most annoying part to upgrade, since you have to rip everything out and then redo it. The 1060 looks to already be a pci-3.0 x16 lanes, I don't know your current mobo but if it is the same then you can just swap GPU with no hassle really.
Low RAM, good news that RAM prices has gone down, bad news is that RAM is labeled weirdly with all the timings so it confuses people. Look up your current mobo see what the developer mentions for speed and timings, buy some of that. For brands, I prefer G.skill, Is one of the most used RAM brands for breaking overclocking records, so has to be damn stable.
Sorry if none of this is helpful, glad you got over your shingles/measles/black plague and welcome back.
