It sounds like a killer deal to me. With an R9 290 or 390 and a total cost of $250 or less it would be hard to beat price/performance.

Saying that an RTX 2060 is a side-grade for a GTX 1060 is just silly. The RTX 2060 is functionally equivalent to a GTX 1070Ti.

There are a lot of aspects to consider when selecting a new monitor, and a lot of them are personal preference. What you are using the monitor for should be a major factor in your decision. For gaming I prefer higher refresh rate over higher resolution so "4K" just isn't really an option unless your budget is close to $2k. My personal preference for resolution is 2650 by 1440 because it offers a nice increase of resolution over 1920 by 1080 while still offering higher refresh rates (100hz+) at a more reasonable price. There is also aspect ratio to consider (to go ultra-wide or not). 1080p and 1440p monitors are 16 by 9 aspect ratio which has become a standard for most monitors but ultra-wide 21 by 9 aspect ratios have recently become popular. There are pros and cons to a 21 by 9 aspect ratio as well (again mostly personal preference). Ultra-wide will give you a slightly higher resolution while still being able to provide higher refresh rate, but the 21 by 9 aspect ratio is not supported by all games (you might want to check the titles you play for support first). The common resolutions for utra-wide monitors are 2560 by 1080 and 3440 x 1440 (the one linked in your post above is 3440x1440). My personal opinion about gaming on an ultra-wide is that I feel "squished" vertically, but I highly suggest you try one and form your own opinion. There are a lot more things to consider including stand/mounting options, adaptive sync/freesync/G-sync, response time, HDR support, color accuracy, brightness, panel type, inputs, viewing angle, manufacturer support/warranty, and input lag. (some or all of the above you may or may not care about which makes the process very subjective) Good luck on your hunt for a new monitor! Below is a link to my daily driver monitor and the reasons why I like it. https://www.amazon.com/dp/B06XT6WQCJ/ref=cm_sw_em_r_mt_dp_U_6opnCbETVM7J5 Pros: 32" size (l prefer larger screens, and actually used to use a TV) 2560x1440 resolution (higher than 1080p resolution without being to much for my pc) 144hz refresh rate (amazing for gaming and not too much for my pc) 1ms response time (prevents ghosting when changing form light to dark) factory color calibrated (colors are great straight out of the box) Vesa mount compatible (mounted to an arm on my desk it does not fill my entire work space) Cons: stand (the included stand is highly adjustable but insanely large. I fixed this by mounting to a gas arm) "HDR support" (this monitor's HDR support is a joke and simply should not be used IMO) freesync instead of G-sync (this could turn into a pro depending on the upcoming nvidia driver update)

If he used it for mining then he likely has multiple cards probably even of the same model, so make sure there is a way to identify that specific card.

There are a lot of people that simply don't like the idea of inviting a stranger into their home. That being said the most important thing to ask is why the person is selling and why so cheap. If they won't answer those questions or the answers aren't what you want to hear then don't buy. You can also ask them to record a video of them testing the GPU. You can also ask the person to come to your home or somewhere that you can test the GPU before you buy.

You'll be fine. if you haven't modified the vbios or done physical mods to the card the manufacturer warranty will cover you.

With most pascal cards you would have to physically modify the card to run unsafe voltages.The power/voltage slider available in overclocking tools such as afterburner and precision etc.. are perfectly safe.

The Maximize 3d performance is the "SLI" settingand it is enabled. That makes me think that Kombuster isn't supporting the dual GPU setup. After doing a bit of reading, it looks like it you have have to run it in full screen but that may not work either. I would find a game with known SLI support and try that.

I know there is no "SLI Bridge" but you do need to enable the SLI technology in the Nvidia control panel.

stupid question, but did you check to make sure that SLI was indeed enabled?

Additional notes on the platform differences. I'm sure I'm forgetting some things if anyone wants to help fill in the gaps or correct me if I'm wrong. X79 (4930k) older platform more PCIE lanes (40) Quad channel memory support (higher bandwidth) no iGPU (onboard graphics) Z97 (4790) newer platform less PCIE lanes (16) Dual channel memory support (lower bandwidth) iGPU (onboard graphics)

What are you doing with the PC? It "might" not be as good in gaming but should be better at anything multi-threaded. The 4930K should be easy to overclock assuming the motherboard is any good, but most X79 boards are pretty good. I personally still use the X79 platform with the Xeon equivalent to the 4930k (E5-1650v2) overclocked to 4.5Ghz and have no complaints about performance. My machine is mostly used for gaming at 1440p 144hz these days.

Get the faster memory as it is proven to help on Ryzen processors.

Yup, but don't expect stellar results. You've got a lot more headache in front of you, regarding drivers and updates. Good luck though.
