So I currently have a Home Plex server. It's in a hot swap 12 bay rack mount case. 4960k cpu , 8 gigs of ddr3 , 850 watt platinum PSU. This also acts as my HTPC. I bought a 1060gtx to go in it , used here of the for sale. Had it for a few months before getting a chance to put it in as we just bought a new house. So I get it back up and running and put the 1060gtx in. All is good for like a week. Then it locks up and wont boot. I removed the video card and it boots up. So I try the video card in the second PCI-E slot and it works fine. Just to make sure I run 3d mark on it for a few hours and doesn't have one issue. Didn't crash or have any artifacts. I was like ok maybe the motherboard is going out. It runs fine in the second slot for a few days and does the same thing. Computer wont boot with the card in. Take it out and still won't boot all the way. But doesn't just stop as soon as I turn it on like with the card in. So I take everything out and reset the bios and get it to work on the built in GPU. So not it's up and running again on the intel GPU. At this point I don't know what's Borked lol. I'm going to take the Video card and run it in a old Dell it have laying around for a while and see if it comes up with the same issue. Now the point. I have 2 dead PCi-e slots in my current setup and maybe a dying motherboard. So it's time for a rebuild. What direciton should I go ? Should I pick up and a new AMD 8 core 3700x or go with a Some XEON CPU's off ebay for it ? All it does is stream movies and Run Kodi with Madvr for my theater room. I at most have 4-6 people streaming off of it at a time. Thanks for the input.
