My current PC is a CyberpowerPC GUA380. I upgraded the GPU to a GTX 750 Ti SC, and the PSU to a Corsair 550w. It has been a while, and would like to upgrade it again. I am going to get the Intel i5 4690k, and the EVGA GTX 970 FTW GPU. Since the GUA380 has an AMD processor, I am going to need a new motherboard. I have also been told to get a new PSU, since the 550W is around bare minimum for the build. I am just looking for suggestions in motherboards, and I guess power supplies. Also, people have told me I am going to have to re-install Windows when swapping motherboards. I have also heard since I am Windows 8.1, I won't have to buy a new Windows. If you have any personal experience doing this, I would gladly appreciate it if you could let me know. I am attaching links to the items so far.
