Im upgrading graphics card from a 750ti to a 1060 and to do this I need a new motherboard. The issue is I have an i7 4790. Does anyone have any suggestions as to which motherboard I can buy around 100 dollars?
Who told you that you need a new motherboard? You might need a bios update or might need to reinstall windows for UEFI boot, but unless it i some really unique model specific issue then any socket 1150 board should be compatible with a GTX 1060.
