So I bought this computer on Black Friday for $600. It came with a 23" monitor and a wireless printer. I have a few questions about it. 1.) Was this a good investment? It seems awesome so far but I want to know approximately how long I can expect this to last. 2.) The graphics card it came with kind of sucks, so I'm thinking about getting a new one. The thing is, apparently it's "Built in" to the motherboard or something. Does this mean I can't get a new one? 3.) Furthermore, the reviews say something about the power supply and how if you wanted to upgrade the graphics card you'd have to get a new one. I really don't understand what this means. Can someone explain it to me, then maybe point me in the right direction to get one?
