Hey guys. As I'm new to PC building I'll ask for help. I'm planning to upgrade my current Nvidia GeForce GT 610 2GB to a new one, GeForce GTX 750 Ti 2GB GDDR5. What other things I need to change in order to run my new graphic card smooth? I have Intel i3 3250 3.5GHz processor and ASRock H61M-VG3 motherboard. Do I have to change motherboard aswell? If I'm correct, I have 350W PSU.
