I'm currently in the process of getting parts for a new computer build. So far I have a Asus Maximus VIII Hero mobo and a Samsung 850 EVO 500GB. M/2 ssd for it. I'm also going to be re-using the Seagate Barracuda 3.0TB h.d , Intel 530 Series 400GB ssd (for Games), Lite On DVD-RW, Lite ON Blu-ray burner and memory card reader from my current pc. I'm also going to be getting a NZXT Phantom 820 case. G-Skill Ripjaws-Z DDR 4 3200 ram (32GBS) and a Corsair HX-1000i psu for the new pc. I need suggestions between the following part's for the new pc. The heatsink is either going to be a EK-XLC Predator 240 or a Corsair Hydro Series H-100i GTX. With either one, I'll be using 4 EK-Furious Vardar FF5-120 (3000rpm) fans in push/pull. I also need help deciding between 2 GeForce GTX 4.0GB or 2 AMD Radeon 390X 4.0GB video cards. I'm ordering a Intel Core i5 6600K cpu on Thursday and eventually plan on upgrading it to a Core i7 6700K in early 2017. Keep in mind, I'm on permanent disability (Social Security) for life and can't afford to spend over $300.00 on a part/s in a month. The pc won't be built until May as I won't have all parts until then minus the new video cards. I'll be using my current GeForce GTX 760's until then, but they need to go back inn this pc, so I can sell it. All suggestions appreciated between the AIO's and video card's. P.S. PC will be running Windows 10 Pro x64.
