I use it for gaming at high refresh rate at 4k. It works well.
I overclocked the i9 9900k to 5.0GHz all cores with 1.320v vcore and a -2 AVX offset. I can't go to 5.1GHz without dangerous levels of voltage. Not terrible, but I definitely did not win any sillicon lottery.
The memory is overclocked to 3700MHz with the default timings of 17-19-19-39. Anything more and I get instability in Prime95.
The graphics cards are overclocked +45 core clocks and +300 memory clocks.
The only nvlink connector I could find in stock was EVGA's. I had to remove the plastic casing from it because it had points that jutted out forwards and it wouldn't fit otherwise. It looks worse, but I don't really care. I opted for a solid side panel and no RGB elements because I'm going for a low key look. In fact, I turned off all the RGB for the components that came with it.
If you just go by the spec sheets, the Fractal Design Define R6 says it can't fit E-ATX motherboards this long, but it can fit as long as you thread all the power cables through the grommets first, and then screw in the motherboard, as the 24-pin connector can not fit through the hole anymore after you install the motherboard.
The cabling is all out of the way in the main compartment to allow good airflow, but the back and what's under the power supply shroud look like a disaster. There's reasons I didn't post pictures of those. But with the side panels on, nobody can tell anyways. It's functional I guess.
Great cooler. Can handle the enormous heat output of a 9900k.
It's a nice motherboard, but at this price range, it should have included more onboard USB2 headers. I ran out and had to buy an internal USB hub.
Frankly, at this price point, it should have had iGPU support and a PCH chip at this price point, too.
The reason I went with this motherboard is it's the only one in this market segment that has 4-slot spacing between the GPUs, which I felt was essential to getting both GPUs good airflow considering how massive they are.
The drive is nice and snappy.
Works well. This is the most massive video card I have ever laid eyes on.
This is an amazing case. The build quality is superb.
One suggestion would be to have a slightly less cumbersome method to ventilate the top. Right now, it's a little labor-intensive to switch between vented top and solid top panel. Something where you just pop the metal panel on and off seems like it could be just as easy to manufacture.
Also, some of the screws were in awfully tight when it was shipped to me. I get that you don't want it to come loose in transport, but I nearly stripped a bunch of screws trying to undo them.
This power supply is much longer than I thought!
Great monitor, but at 4k 144Hz, you have to use 4:2:2 chroma subsampling, which makes text (or anything high contrast, really) look like garbage.
It's really a 98Hz monitor if you want full chroma and HDR. And it's 120Hz if you are willing to give up HDR. As far as I'm concerned this is a 120Hz monitor, because it's just too jarring to look at the subsampled chroma channel.
It's not Asus' fault, though. It's the cabling standard. DisplayPort 1.4 just can't push enough bits to make 144Hz HDR at 4k.
Great keyboard. Nothing left to be desired.
Edit: After using it for a month, I've changed my opinion about the Orbweaver. It's comfortable and very solidly-built. It took a little getting used to, but I'm now quite happy with it. I've been mostly playing simpler games that don't have as many inputs, and for that purpose it's tolerable, but you could never play a complicated game (like World of Warcraft for instance) with this. There just aren't enough buttons. I'm leaving up my original review below:
Original review: This was much less comfortable to use that I thought it would be. What I really wanted was something like the Steel Series Merc Stealth which I used several years ago and I absolutely loved. (https://www.amazon.com/SteelSeries-Merc-Stealth-Gaming-Keyboard/dp/B00292OW1U) It was much more ergonomic. Steel Series no longer makes this, and it's not mechanical either. I don't know what I'm going to do with the Orbweaver. Maybe I can get used to it.
I love the short travel distance and clickiness of the left and right buttons. It feels like the mechanical keyboard of mice.
I guess these are good? I'm not really much of an audiophile, so I can't really tell. They are comfortable to wear for long periods of time.
Does its job.
Solid? Does its job.
It worked. Did exactly what it claimed to do. I was able to overclock these to 3700MHz, but no further.
