[SOLVED] Cpu+mobo comparison core count vs single threaded performance (xeon cpu)

Nov 1, 2018
looking to build a system from used eBay components. I know what other components I am using but I am a little stuck at the cpu and motherboard. I can spend up to $150 with the cpu and motherboard but I would like to go closer to $100. I will use this computer for animating and rendering/editing video projects, streaming and playing games, and doing general web browsing and school work. I am debating whether to get a xeon x5680, E5 2670 v1, e3 1225 v3, or an E5 1620 v2. I am also using the cooler master q300l micro atx case but I can also change this. my gpu that it will be paired with is a gtx 1060 6gb. here is some information that I've compiled for each option.

- lga1366 socket
- with motherboard I'm using (hp truckee mobo), 6 ram slots with up to 24gb ram (4gb dimm 1333mhz per slot max)
- passmark single threaded performance of 1438
- 6 core 12 threads
- Clockspeed: 3.3 GHz, Turbo Speed: 3.6 GHz
- bios updates are tricky with this mobo
- no io shield, sata cables, usb 3.0, and no 4 pin fan headers
- supports sli (2 pcie x16)
- total cost of cpu+mobo =$105

e5 2670 v1:
- lga 2011 socket
- Chinese motherboard supports up to 64gb ram (4 slots)
- 1 pcie x16 2 pcie x4 usb 3.0 header, 4 pin fan headers, sata cables, Driver disc, io shield
- Clockspeed: 2.6 GHz, Turbo Speed: 3.3 GHz
- 8 cores 16 threads
- passmark single thread is 1574
- total cost = $135

e5 1620 v2:
-lga2011 socket
- same motherboard and specs as e5 2670
- Clockspeed: 3.7 GHz, Turbo Speed: 3.9 GHz
- Single Thread Rating: 1959
- 4 cores 8 threads
- total cost = $120

e3 1225 v3:
- lga 1150 socket
- has several motherboard options including cheap asus motherboards that are very good quality ($50 deluxe)
- not as good of a cpu as the others, main benefit is reliable and trustworthy motherboard
- Clockspeed: 3.2 GHz, Turbo Speed: 3.6 GHz
- 4 cores, 4 threads (no hyper threading)
- Single Thread Rating: 2016 (best)
- total cost =$100

main attractions for each
x5680 - cheapest combo and supports sli
2670 - most cores
1620 - higher clock speed and single thread rating than 2670 but half the cores
1225 - good motherboard

I would like some assistance to help point out anything I might be missing and whether more cores or better single thread performance are the smarter option. Also any other cpu + motherboard combo ideas in this price range would be very welcome.

So you want me to build this system...? I have a total budget of about $400 or a bit less.
Another FYI on these. The first CPU has 6 RAM Slots, the 2nd CPU riser has 3. So 3 channel configurations for 2 CPUs are 3x4GB, and 3X4 GB each CPU for 24GB.
Or 6x4GB and 3X8GB for 48GB (upgrade fron 24GB). Or 3x8GB and 3X8 GB for 48GB. It takes UDIMMs which can save some money, and up to 96GB is possible using 16GB UDIMMs
