Hey guys . I wanted to know which one of the following rig can play Watch dogs on ultra and would be more future proof as upcoming games would require more than 4 cores . I won't be overclocking if its i5 4570 + r9 280x and will overclock if your suggested rig is other than i5 4570 + r9 280x . Will do crossfire or sli in future.. I want this rig to last me 4 years before any upgrade.
