I bought a prebuilt pc back in 2016, and it is time to upgrade. Was looking to get a new motherboard, as the one I have right now only supports amds fx series of processors and ddr3 ram. I was also needing to get a new processor and decided on an i7 7700k, right now I have an fx 8350. I also need a new gpu, and decided to get a gtx 1080 ti. The gpu I have right now is a gtx 1060 3gb. So what I need is a motherboard that supports at least 8 gb of ddr4 ram, and supports both gtx 1080 ti, and i7 7700k. I also need the mother board to fit in my tower. My tower is a thermaltake n21 black. Also, my power supply is 500 watts. Do y'all know of a motherboard that fits my needs?
