If you are looking for the best specced Mac for less than £800 only the Mac mini will do. If you have slightly more to spend, say up to £1,000, you could spec up the top of the range Mac mini with a 3.0GHz processor, and take advantage of the Fusion Drive (giving you the best of both worlds). This would cost £959. While an equivalently priced MacBook Pro would offer a 2.7GHz processor and 128GB storage for £999.
So if you already owned a screen, and have £1000 to spend, we'd recommend the Mac mini. Although we'd advise waiting a few months as we think Apple will update the range very soon.
That's presuming that you don't need and want a portable Mac, if that's the case we totally recommend the MacBook Pro with Retina display.
The best value way to buy a Mac might just be to purchase a second hand Mac. There are a variety of ways you can do this, check the Apple Refurbished store here, where Apple sells Macs that have been returned (if there was a fault it will have been rectified and the Mac still has a one year warranty). You may also find a good deal on eBay or on Macworld's own mResell site, where we buy and sell old Macs, iPads and iPhones.
