Im planning on building a pc for gaming and a bit of video editing. I would like to reuse as many old parts as possible to save money, but I dont want to end up with a system that I will regret not spending more on. My current pc has a fx 4300, a 500 gb hard drive, a firepro v4900, 500 watt psu, a motherboard with a cpu limit of 95w and only 6 cores, and 4 gb of ddr3 1333 ram. My budget is about 800 dollars, but I can scrape up a few more dollars if I need to.
