So, i just recently purchased a gigabyte gtx 1660 super and was wondering if i should update my BIOS?
Will it be effective in any way or will it not matter?
Would depend on your motherboard. What are your full system specifications; to include the make and model numbers of both your motherboard and power supply?
You only need to update your bios, for CPU compatibility, or if there is some kind of performance/stability benefit to it. I also second that you need a better quality PSU.
You'll get differing opinions here. Mine is, "If it ain't broke, don't fix it". A failed BIOS update can cause serious headaches. It'd be a real bummer to lose your PC for a few hours/days because of an unnecessary update that failed.
