(imaginative title i know) Now i work with macs all the time, I support an apple xsan, but I don't actually own one myself (my previous work supplied me with a laptop to work from home with but my new role doesn't supply one) However I do want to buy a mac to work with at home, and replace my ageing windows desktop that is a gaming machine. However I'm in a bit of a pickle. Basically apples complete lack of any decent graphics cards, anywhere in the lineup. THe only thing that comes close to what i want is a mac pro, I was thinking of getting the 6 core as it seems the most capable/affordable, but may go to an 8 core 2.4 as pc world (/spit) have some available for £2k. Now I've read that osx 10.8 supports the 5xx series cards quiet well. Would i be better off buying the mac pro with a ati5770, and swapping in a nvidea 560, or should i splurge for a 5870? I've looked at getting a macbook and a separate gaming pc, but that ends up costing more.
