I'm looking to ditch my 2ghz c2d Pc in favour of a Mac and have been trying to decide for months. Now the new refresh is out it leaves me with new questions! I will use it for photo and a bit of video editing, general browsing and a bit of gaming. I'm left with these choices, what is the best value? 27" 3.2 i3 with 512mb 5670 for £1399 27" 2.8 i5 with 1gb 5750. for £1649 Or the previous returns 27" 2.66 i5 with 512mb 4850 for £1269 27" 2.8 i7 with 512mb 4850 for £1399 To me the i5 refurb seems to be the sweet spot but is the i7 worth the extra and how inferior is the graphics card compared to the latest refresh? I'm sure I'll see enough perfomance out of any of the cpu's but want this to last as long as possible.
