You can stream through the GPU without loosing any performance, the new nvidia cards can do 4k/60FPS and more all day long and you won't even notice any performance degradation.Thanks for the suggestion. My budget allows me to get 1x16gb 3200 RAM for now. I guess that should help me in running the games. As for streaming, may be I can wait for a month and get another 16gigs 3200 stick.
I hope this single set up with AMD processor works.
