I built a new computer in 2009, and it was a very nice computer. Then I tried to replace it in 2015 with a much newer computer, but kept the old one around as a backup. The newer computer died after about a year (or more specifically, the motherboard died), so I took some components out of it, stuck it in the old computer, and had a working computer again. I figured I'd get around to doing something better when the now-upgraded older computer was no longer good enough. That still hasn't happened, but I want a new computer anyway.
I'm not meaningfully budget limited, so I can pretty much buy whatever I want. It's for home use, including gaming. My unusual requirement is that it has to handle three 2560x1440, 144 Hz monitors in landscape mode for a combined resolution of 4320x2560. I already have the monitors, and they were what drove my upgrade in 2015.
Here's what I'm looking at:https://www.newegg.com/Product/ComboBundleDetails.aspx?ItemList=Combo.3793256
A Ryzen 7 2700X, together with an X470 motherboard. You could argue as to whether that or Coffee Lake is better. The difference probably won't particularly matter in the useful lifetime of the computer, however--and if it does, Socket AM4 has two more generations of upgrades coming, while Intel will probably require a new socket. I would bet on the fastest Socket AM4 CPU that ever will be built (likely based on Zen 3 and launching in 2020) being markedly better than the best that will ever fit a currently available Coffee Lake motherboard. It's also incontestable that the Ryzen 7 2700X is cheaper than a Core i7-8700K with a comparable build, in part because of the next paragraph.
I'm also going to use the stock CPU cooler. AMD's Wraith Prism CPU cooler is massively better than the junk that Intel ships as their stock coolers. It's not going to make $80 coolers obsolete, but it's competitive with what you might get for $30. And it's "free", in the sense of being included with the CPU.https://www.newegg.com/Product/Product.aspx?Item=N82E16820313799
Ryzen has been finicky about memory support, so I picked a memory kit on the official support list for the motherboard. I want 1.2 V, as I don't want to overvolt the memory, and that seems to largely only be available up to 2666 MHz, so that's what I got. I wanted 2x16 GB for 32 GB in total, but the official support list doesn't say that configuration is supported, so 2x8 GB it is. If I eventually actually need 32 GB, it's easy enough to upgrade later.https://www.newegg.com/Product/Product.aspx?Item=9SIADF17442836
That would be 960 GB of NVMe over PCI-E SSD storage. I've often scoffed at the advantages of getting a relatively faster SSD over a relatively slower one, at least now that the early, terrible drives are long since off the market. But if I'm not meaningfully limited on budget, why not?https://www.newegg.com/Product/Product.aspx?Item=N82E16814932031
Why AMD rather than Nvidia on an unlimited budget? After all, a Radeon RX Vega 64 isn't competitive with a GeForce GTX 1080 Ti at top end gaming support. The answer is multi-monitor support. Plug in 3 monitors to a single GeForce card and it runs at the max clock speed, even at idle. Run a monitor at above 120 Hz and it again runs at the max clock speed, even at idle. My required use case is three monitors at 144 Hz, and my current Fury X has no problem with clocking down to 300 MHz with that setup, not merely at idle, but even while playing very undemanding games.https://www.newegg.com/Product/Product.aspx?Item=N82E16817151172
Top end Seasonic quality in a 650 W package. I didn't feel like paying extra for Titanium efficiency. Platinum is good enough.https://www.newegg.com/Product/Product.aspx?Item=N82E16811147237
Last time I built a computer, I decided to pay more for a nice case. And regretted it, as the Corsair Carbide 400R that I bought was markedly inferior in several ways to the older and cheaper Antec Three Hundred that I had used for my previous build. Rosewill has attacked the market with some budget-friendly cases with plenty of airflow for gaming rigs. I'm curious if they're any good, but there's one way to find out.
I bought the full version of Windows 10 with my previous computer. Since that computer died, the license isn't still in use. So I can legally reuse it on the new computer, and plan to do that.
For the most part, I'm not getting new peripherals. I'll probably grab a new mouse or two, though, as my current one seems to be on its last legs after about nine years, and I don't want to be left without a working mouse if it dies. All I want is two buttons and a scroll wheel, as I don't play mouse-heavy games for fear of repetitive strain injuries, but the mouse needs to reliably work right.
And no, I haven't already placed the order. Because buying hardware, and then asking for feedback after it's too late is stupid.
