OK, so after more research, I was able to frame my questions better HERE
for the GPU issue and then after determining that a separate monitor is more helpful than a 3DTV which can only connect via HDMI and is thus going to be limited to the resolution of 1080P and so the monitor issue was addressed HERE
If other newbies view threads like this and wonder why they aren't responded to, i think it's because I was WAY too vague (mostly by not listing the information about the power supply unit) But once I was able to focus my questions I got prompt and helpful responses! Good luck to everyone out there searching for answers.....
BTW -- if someone wants to/can close this thread, that'd be fine
