Mid-tier Ryzen 2000 series build to replace 7 year old FX-6300 build. Intended usage for just about everything including content creating (video, photo work, rendering), 'deep learning' learning, 1080p gaming, and general work (office apps, web browsing). Budget for this build was ~$1,100 before tax and shipping.
Debated between the 3rd generation Ryzen 5 3600 and the 2nd generation Ryzen 7 2700x at the $170 price point. Ultimately selected the 2700x as it didn't seem like better single-core performance improvement in the 5 3600 for 1080p/1440p gaming outweighed the significant boost in multi-threaded performance from having extra cores for rendering and video work. Will see how the 2700x fairs with the stock wraith prism cooler; may upgrade this later.
Spent a lot of time researching motherboards and chipsets. Ruled out x570 chipset quickly due to price and lack of real benefit over B450/X470. I really liked the B450 price points and most of my research led me to consider the MSI B450 Tomahawk Max (@ $124) or B450 Carbon Gaming Pro (@ $149)... but ultimately went with an Asus ROG Strix X470-F. Hoping that the ~$40 premium for the X470-F is worth it for better VRM thermal performance, audio (in case of the B50 Tomahawk Max) and potential to run the last generation of Ryzen AMD4 socket CPUs (bios willing). I also looked at other x470 boards, but with Coronavirus mucking up supply chain availability, couldn't find decent alternatives in stock at "normal" prices.
Somewhere along the line, I got hooked into the believe that RGB makes everything better... so I of course had to pay a few extra bucks on the GeIL EVO X II RAM sticks to go with the RGB version. I stuck with 16GB as this is adequate for gaming and probably adequate for the toy datasets I'm playing around with for my 'deep learning' dabbling because... hey, I had to control the spending somehow. Plus RAM is easy to upgrade later.
After debating the merits of going with a WD SN550 Blue NVMe M.2 drive versus either a WD SN750 Black or a Samsung 970 EVO, I figured the better performance of the Black/EVO was worth the $15 for my main drive. (I'm planning to use a few SATA SSD's I have lying around for additional 'bulk storage'.) The WD SN750 and Samsung EVO seem pretty well matched, so I ended up with the SN750 as I was able to grab it for $15 less.
Speaking of 'deep learning', I spent an $100 or so extra for a RTX 2060 Super over a GTX 1660 Super (or Ti) for the former's tensor cores. Thought about going for a RTX 2060 at around $370, but figured the extra 2gb RAM might be helpful for Kaggling or whatever. Plus the 2060 isn't so widely available now. So far, happy with the ROG Strix RTX 2060 Super I got for $409 after promos. Plus RBG bling! There goes another $20...
For the case, inexpensive (but not 'cheap') was the guiding principle. I still occasionally use optical media, so that pushed me to the Cosair Carbide 110R as it is one of the few cases still readily available with an external 3.5 optical drive slot.
I'm taking a flyer on the EVGA SuperNOVA GA 650 80+ Gold Certified power supply at $74. The EVGA GA series is new and not too much written about them yet. Comes with a 10 year warranty so probably won't blow up, even if power delivery isn't quite as good as the G2/G3 series manufactured by Super Flower.
I have another one of these drives in an older build I use as my "Media Center". Purchased this one used on Ebay to save a few bucks and so I didn't have go through 'downgrading' the ROM to v1.02 in order to read 4K UHD discs. If you aren't lazy like me (and care about being able to read 4k discs as inexpensively as possible), it isn't too hard to side load the 1.02 ROM (Google it). Even new, great drive for the price.
Finally, I grabbed a six pack of upHere RBG 120mm fans to keep things cool (because of course the assortment of existing non-led fans I have hanging around will simply not do). In the past, I've always gone with more expensive fans from the likes of cooler master or corsair, but really didn't want to pay a $100 bucks for a few RGB fans. So far, they seem to be doing ok (and quieter than I expected). Here's hoping these inexpensive fans don't start throwing out to much RF interference or suffer from premature bearing fail.
