1 machine is running an i7 920 - can't be overclocked. Other machine has a g3258 running @ 4.2ghz. I have a 6970 video card. I know neither setup is high end but one machine will run 24/7 as a media server (serverWMC, sharing out recordings, movie files, etc) other machine will be for kids to game on. The 6970 will go in the gaming machine. Which setup to put the video card in? Thanks in advance.
