A few weeks ago, Apple updated its iMac desktop line with 'Retina' displays—an Apple marketing term used to denote LCDs with a pixel density high enough that individual display elements are invisible to the unaided eye at typical viewing distances. On Apple’s iPhones, the 'Retina' moniker means a PPI of at least 300; for MacBook Pro portables, it means about 220. The new iMac’s 27' 5120x2880 LCD panel has a PPI of 218, putting it just below the 15' MacBook Pro’s 220 PPI.
I've been a PC user my whole life and even though I'm a huge iOS guy, I've never had a Mac - primarily because I'm a gamer. Well, my PC is starting to get long in the tooth and I'm also getting tired of Windows, so I'm thinking about jumping to an iMac as soon as Apple refreshes them in 2017. Can they be used for gaming? Apr 03, 2017 No. Absolutely not. I own a 2013 Mac pro, the trash can model. Sadly, the most powerful Mac that exists. Fully upgraded, with dual d700s. People will love to tell you that as long as you have the equivalent hardware, your experience will be the sa.
Those numbers translating into a stunning screen is unsurprising, and now that I’ve got one on my desk to play with, I’ll absolutely add my voice to the chorus of other reviewers saying that the new iMac looks amazing. I haven’t yet attached a colorimeter to the display and gone to town—that’s coming in the next few days—but here’s the color space information right out of the box:
In spite of how sharp and beautiful the screen looks, I was hesitant as I pulled the thing out of the box. After all, I’m that rarest of rare birds: a PC gamer who also happens to do most of his gaming on a Mac. My personally owned desktop is a 2013 iMac with all of Apple’s built-to-order options checked (except RAM, of course—there’s no reason on a desktop computer to pay the Apple tax on RAM when third-party stuff works just as well), which couples a 3.5GHz Haswell i7-4771 CPU together with a 4GB GeForce GTX 780M. It’s certainly not the fastest gaming rig, but it’s more than enough to drive the 2560x1440 display at native resolution with high settings (along with AA and AF) in most games.
In spite of the strides OS X has taken in recent years, though, I do the majority of my gaming booted into Windows. I’ve resisted the idea of a Retina iMac for years because of the potential impact it would have on gaming performance. It’s one thing to stuff a video card into an iMac that’s powerful enough to smoothly display the OS X interface with the resolution-independent scaling tricks the Mac does these days—but it’s quite another to reboot into Windows and actually try to game at native resolutions.
So that, dear readers, is precisely what I did when my review iMac arrived on Saturday. I unboxed it, snapped photos—after a few years working at Ars, I now compulsively photograph basically every piece of gear I unbox, sometimes without even realizing I’m doing so—and then fired up the Boot Camp assistant to get Windows 8.1 installed.
The hardware
Apple sent us an upgraded review iMac. Our review unit trades in the stock 3.5GHz i5-4690 CPU for a quicker 4.0GHz i7-4790K, along with a quicker Radeon R9 M295X GPU (replacing the stock R9 M290X). The two additions each tack $250 onto the iMac’s base $2,499 price, bringing the total up to $2,999 (plus tax, depending on your location).
This is a steep price to pay for a desktop computer, but don’t forget that 5K screen. A similar panel from Dell is expected to run you $2,499 just by itself when it becomes available this quarter.
Cinebenching it
Before departing for the land of Windows, I wanted to quickly hit the new iMac up with Cinebench, a free and readily available cross-platform graphical benchmarking tool that we’ve used before on desktop devices. Straight away, the Retina iMac’s Radeon R9 M295X and i7 posted much higher numbers than my loaded 2013 iMac:
With these numbers out of the way, I bounced into Microsoft-land.
Back before 2006 (which is like 100 years ago in the technology industry), there was a clear dividing line between Macintosh computers and PCs. Mac OS couldn't run on PCs, and Microsoft Windows couldn't run on Macs. This created a great rift between users of each system. It wasn't unusual to hear heated arguments between two users about which was the better system. A few brave souls tried to take an all-inclusive approach by trying try to run both using virtualization software, but even that presented limitations. If you wanted to use the full features of both operating systems, you'd have to buy both a Mac and a PC.
But in 2006, that all changed. Because in 2006, Apple began moving away from its PowerPC processors and offered Mac hardware with Intel processors like those used in PCs. This introduced the possibility that Windows and Windows-based applications could run on Mac hardware just as they run on PCs. At the same time, Apple released Mac OS X Tiger (10.4), the first Mac OS to support running on Intel processors [source: Apple, Buchanan].

Boot Camp is software developed by Apple, in cooperation with Microsoft, designed to effectively run Windows on Mac hardware. By using Boot Camp, you don't have to choose whether to install either Mac OS or Windows. Instead, you can install both, and you can switch between them just by rebooting and selecting the other OS.
This article covers how Boot Camp works and how you can set it up on your Mac. Boot Camp has been available as part of Mac OS X since Leopard (10.5), released in 2007. The latest version of Boot Camp as of this writing, Mac OS X Lion (10.7), supports Windows 7 Home Premium, Professional or Ultimate editions [source: Apple].

Before we dive into Boot Camp, let's look at how the partitions work on your Mac's hard drive, and how the Mac knows which partition to use when you boot.
