I'd really like help figuring out a good upgrade path to turn this into a beast. The motherboard and cpu are showing their age and the stock cooler has trouble keeping it cool under load. Even the RAM is clocked pretty low from what I understand. I work part time and bring in about 600 a month, about 200 of which I can put away. With cyber monday/Christmas sales coming up I'd love to cash in on some really good deals. You'r wisdom is appreciated. The computer components are important but a good sound system/pair of headphones, and peripherals in general are gonna become more important as time goes on. I'm in the US if that's important. I'm a CS major and I like messing around with all sorts of content creation software. Blender, LMMS, Unreal, programming IDEs, video editing, photo editing, stuff like that.
