So im looking to upgrade my PC very soon because I plan on doing Youtube and Twitch Streaming. Right now i have a EVGA 750 ti sc(i know its nothing fancy but graphics is not that important to me), AMD 5400k CPU, 350w PSU, 8gb of RAM, 500gb HDD, and the MOBO is an AsRock FM2 DGS. What im really concerned about is the MOBO and CPU because i know those 2 are definitely lacking(maybe the PSU is too??). So does anyone have any recommendations on upgrades? And if its in the budget, what about a Keyboard too?
