I can get good used 2 year old desktop computers at around $30-$50 form the ex Government IT Auctions. All they normally need is Decent Video card at around $50 local money and your away. Maybe it is something you can look into in your area. Most are high spec with lots ram PC's
There is no such thing as a decent video card at $50. At that price point a new GPU is generally in the region of the Geforce GT720's and the like. Low performance with a poor performance to cost ratio to boot.
At this moment in time with multi threading still not being properly implemented in games, the likes of the Athlon II 860K and the Pentium G3258 are excellent budget options for the CPU. RAM wise with costs as they are and utilisation not really increasing for the time being, 8GBs of DDR3 will suffice for now and into the future depending on personal usage. You buy as much as you think you will need alternately. With the GPU there is a wide range of options from the Radeon R9 270X all the way to the Geforce GTX970 that offer great performance with respectable performance/cost ratios. It is important to match the GPU to the CPU to avoid bottlenecks of course. Storage wise a mechanical hard drive for mass storage and an SSD for boot is the current norm while the cost per GB for SSDs continues to fall.
