I have a build that consists of an MSI z87-g43 haswell with an i5 4430 and evga 500 psu. My case is falling apart and the fans are dieing so I was gonna order a new case, but I was looking at an upgrade kit of either Intel Core i5-6500 6M Skylake Quad-Core 3.2 GHz LGA 1151, GIGABYTE LGA 1151 H110 Micro ATX MB, Team Elite Plus 8GB DDR4 2133 MEM for $293.....or Intel Core i5-6600K Skylake Quad-Core 3.5Ghz CPU, ASRock Z170 Pro4 LGA 1151 ATX MOBO, G.SKILL NT Series 8GB DDR4 2400 MEM for $372....or should i just order the case and hold off on upgrading due to these upgrades from what I have being so negligible?
