I built this back a few years ago when i was brand new to PC gaming. I still do not have a good knowledge of whats good and whats bad. This PC is not keeping up with todays games (obviously because its old and wasn't top of the line a few years ago anyways) I was looking to sell this and then start over but looking online and todays current builds I see a lot of gaming rigs still useing things like the Intel I5, the power supply I use and im seeing if maybe i just need to upgrade a few core components. Looking at the current list I was thinking the biggest area of improvements in order are the motherboard, the RAM and the video card. What are come compatible build i could do to make this pc better as a whole for gaming?
