Looking at the various components available in desktop pcs has me thinking, and thus looking for some more experienced thinkers. Say I had a machine (leaning to Ohio's systemax, or maybe dell) with a multi-core cpu, fit with sufficient memory, hard drive, video card, and dual tv tuner card, with an hdmi port. It has windows7 os, and it's in our office, with a LED monitor. We have a plasma tv in another room, one 25' hdmi away. Is it possible for my kid to do homework online, or to load photos to facebook with this prospective computer while someone watches cable tv or streaming video and/or records tv to hard drive simultaneously with the same machine ? Can someone help a ham-handed laborer into the 21st century ?
