Meh... My personal idea is to go onto ebay and buy a used Dell Optiplex with at least an i7 like this one: http://www.ebay.com/itm/Dell-Optiplex-990-MT-Mini-Tower-Core-i7-2600-3-4GHz-4GB-80GB-Win-7-Pro-1-Yr-Wty/191605114746?_trkparms=aid%3D555014%26algo%3DPL.DEFAULT%26ao%3D1%26asc%3D41451%26meid%3D84876522c7c14af5a034bd587856eebc%26pid%3D100505%26rk%3D1%26rkt%3D1%26&_trksid=p2045573.c100505.m3226
Then buy a new psu, bigger hard drive, more ram, and a gtx 1080
