Well I used to "overcook"
Even with manufactures now engineering their hardware to perform at “overcooked” specs, they still won’t provide a warrantee if you do over clock them. Plus, I personally hate the smell of burning plastic in the house and the sight of smoke coming from by PC. I won’t do that again … LOL
I now religiously pay for the best performance rather than try and make a lower spec’d component perform at a higher specs.
