Some advice on upgrading my Core I5 2500k

[ghuk]

Hi chaps

Need some advice, I purchased a motherboard package from Overclockers UK many years ago.

My PC spec is as follow, I've added bits & pieces over the years:

Core i5 2500k (Overclocked to 4ghz) + Corsair H80i CPU water cooler
Gigabyte GA-Z68AP-D3 Motherboard
32GB DDR3 Ram (9,9,9,28)
Pallit GTX980
Acer G Sync Monitor @ 1920 x 1080
Various Hard Drives
Windows 10 (64 bit)

When I purchased the Motherboard package it came with a file preinstalled in the bios to run @ 4ghz. However I'm getting the feeling that my i5 is holding my frame rate back in certain games (Witcher 3 as an example) so I'm debating whether to pick up a second hand Core i7 3770k. I don't want to bin my Sandybridge set up as starting over again is a sizeable investment and especially in the current climate probably not the smartest option.

To install an i7 I will need to upgrade my motherboard bios to version F8 according to the Gigabyte website, however what I'm not sure about is that if I do this will I automatically lose the overclocked file that was installed?

Any advice would be much appreciated as I have no clue whatsoever how to overclock a CPU

Cheers
George

Thanks mate

Out of interest did you notice a drop in temperatures with the i7 compared to i5? Just noticed its a 22mm.
