Awesome design and build quality ; Very cool and quiet ; Plays games decently ; Convenience ; Great screen

Mediocre webcam ; Default colour settings not great ; Price

Finally, while the glass front means this isn't a true professional class screen, reflections aren't anything like as bad as you'd expect. This is largely down to changes introduced last year, namely an improved coating and tighter air gap, but the...

Haswell processors ; 802.11ac ; Beautiful slimline design ; Nvidia 7 Series graphics ; Good custom build options

No optical drive ; Limited upgrade options ; £50 or £100 more expensive than last year ; No Hyper Threading on standard processors ; Didn't get a Retina screen option

Fast, beautifully designed, graphics power, Fusion Drive is great, thin design and small footprint for a 27-in screen

Not really upgradable, screen could be higher res, can be fiddly to use slots around the back

The 27-inch iMac is available with a 3.2 GHz quad-core Intel Core i5 with Turbo Boost speeds up to 3.6 GHz and Nvidia GeForce GTX 755M for a suggested retail price of £1,599. Our review unit would cost an impressive £2,229 thanks to its 3.5 GHz...

Attractive design; Stunning display; Haswell update and improved graphics; Thunderbolt ports

Expensive; Limited serviceability; No optical drive; Fusion drive not standard

The iMac’s design is in a class of its own, performance is strong and display near faultless. But PC vendors are catching up and are starting to offer better value alternatives.

While the new iMac looks the same as last years, we don't have any issue with that. It's a gorgeous piece of kit and feels far more premium than virtually every other desktop computer.

Stunning, low-glare display ; Improved graphics performance, disk speeds ; Attractive design ; Robust audio

No optical drive

We already loved the iMac for its attractive design, forceful audio and sharp, low-glare screen, so it's even easier to recommend it now that it's been upgraded with new processors, more powerful GPUs, faster 802.11ac WiFi and speedier PCIe SSDs....
