I made a terrible choice for my first PC deciding to just go with an overpriced prebuilt (Alienware) it's lasted me a long time but I think it's time for an upgrade. I'm looking for a PC with a budget of $1500. I would prefer if it was lower but I really want to have this PC to last a good amount of time. Also I have an i7-3770, GTX 960, 2TB Harddrive, and 16GB of ram. Could I use some of that on my next PC or no?
