I have this Dell Optiplex 330 desktop full size tower that currently is a 2.0 Ghz processor with 1 GB Ram and 250 GB hard drive and I believe it's a crappy Intel hd graphic card. It is running linux mint cinnamon 17 and I seriously need some major hardware upgrades. It is a 32 bit system and I really want to see what I can do on a $570 budget to make this pc have a lot of speed and power and decent graphics comparable at least for 720p or higher. I want to know what ideas there are for even turning this into a 64 bit is I can install windows 8 on and change the motherboard and cup, get at least 8 GB ram. Please send me some part ideas?
