John Burek Executive Editor and PC Labs Director

My Experience

I have been a technology journalist for almost 30 years and have covered just about every kind of computer gear—from the 386SX to 64-core processors—in my long tenure as an editor, a writer, and an advice columnist. For almost a quarter-century, I worked on the seminal, gigantic Computer Shopper magazine (and later, its digital counterpart), aka the phone book for PC buyers, and the nemesis of every postal delivery person. I was Computer Shopper's editor in chief for its final nine years, after which much of its digital content was folded into PCMag.com. I also served, briefly, as the editor in chief of the well-known hard-core tech site Tom's Hardware.

During that time, I've built and torn down enough desktop PCs to equip a city block's worth of internet cafes. Under race conditions, I've built PCs from bare-board to bootup in under 5 minutes. I never met a screwdriver I didn't like.

I was also a copy chief and a fact checker early in my career. (Editing and polishing technical content to make it palatable for consumer audiences is my forte.) I also worked as an editor of scholarly science books, and as an editor of "Dummies"-style computer guidebooks for Brady Books (now, BradyGames). I'm a lifetime New Yorker, a graduate of New York University's journalism program, and a member of Phi Beta Kappa.

The Technology I Use

I use a lot of computers on rotation in my daily work, but I rely on just a few to get things done. I split my work life mostly between a Microsoft Surface Laptop 3 (a 15-inch Ryzen model), paired with a Lenovo ThinkVision portable monitor, and a custom-built big-chassis Windows 10 desktop PC that has served me well for years now. (Specs: Liquid-cooled Intel Core i7-6950X Extreme Edition, 32GB of RAM, and a GeForce GTX 1080 card.) That's all in a giant chassis with six hard drives and SSDs packing its bays. (As I upgrade systems, I just keep moving the old warhorse drives over.) This behemoth is hooked up to a 32-inch LG monitor.

I also have a bunch of PCs around the house, all custom builds: another one attached to my main TV (for gaming and occasional forays into VR), a mini-PC on the bedroom TV (acting as a media server), and a Mini-ITX desktop in a corner of the living room...just because. I carry around an oversize OnePlus phone, but when I do long-haul travel, a vintage iPod Touch comes along, too, for old times' sake.

I wasn't always a PC guy. I cut my teeth on a cassette-drive-equipped Commodore VIC-20 in the 1980s. But I got serious with Apple desktops in the early 1990s, starting with a Macintosh SE, then a Macintosh LC, and finally one of the short-lived Umax "clone" Macs, before building my first PC and never looking back.

With all my typing and editing work over the years, I've become a huge proponent of thumb trackballs, which minimize wrist action (and my wrist pain). I have a secret cache of the long-discontinued Microsoft Trackball Optical Mouse (my personal favorite), held in an undisclosed location.

My Experience

I have been interested in science and technology for as long as I can remember, spurred on by a fondness for video games. I learned to work in Windows and manipulate files to get buggy games to work, and I learned to build and upgrade PCs for better performance.

In my role at PCMag for the past four years, I’ve deeply enjoyed the opportunity to share my knowledge and expertise. Before PCMag, I wrote for Tom's Hardware for three years, where I covered tech news, deals, and wrote some hands-on reviews. After working as a PCMag contributor for a time reviewing desktops, PC cases, budget processors, and motherboards, I now focus on testing and reviewing processors and graphics cards and sharing my insights on the industry.

The Technology I Use

As a PC component reviewer, almost every PC I use is a custom-built system. The only exceptions are my laptops, which I modify and tweak to improve performance, too. My current best laptop is a 16-inch Lenovo Slim 5 with an AMD Ryzen 7 7840HS processor and an Nvidia GeForce RTX 4060. My home-built desktop has an AMD Ryzen 9 9950X processor with an Nvidia GeForce RTX 5080 GPU—all the better to play Kingdom Come Deliverance II with.

My lifelong love of computers and gaming has led me to amass a collection of old tech devices. I have several custom-built PCs, ranging from a Windows 98-based Pentium II to modern hardware, that I use to enjoy older games. These sit alongside my collection of retro game consoles, which includes an NES, a Super Nintendo, a Sega Genesis, an original PlayStation, and a first-generation Xbox.

I'm also a connoisseur of budget tech devices, like my smartphone of choice. Currently, I use a Poco X7 Pro that I bought in 2025 and love so far.
