Greeting knowledgeable ones! Just picked up my first Mac but now I've got it home am having some doubts on if it was the right call or not so thought I'd ask the experts here on MacRumors what they think! Basically I went in to buy either the higher end 21.5 or the lower end 27 (both the same spec, just an extra thunderbolt and a few inches of screen to differentiate them as far as I know?) and after spending a bit of time on each pretty much decided on the 21 as the 27 was a "bit much". Then whilst the sales guy was checking the stock he said that for the same money as the 21 he could do me a 27" clearance model they had, telling me it had a faster processor, better graphics card and of course the bigger screen. It wasn't ex-display or anything, just old stock out the back. Long story short that was the one I went home with - a 27 quadcore 2.8 i5 with ATI 5750 1Gb graphics but now I am home I am really wondering if I made the right decision as this is now already succeeded year old tech and for the same money I could have bought this years model (and nothing playing in the back of my mind!) What to do - these things aren't cheap and I should get the best out of my hard earned but am I getting the best bang for my buck with year old tech? Thanks for listening!
