I realise this is going to be a reoccurring theme on here now but some advice would be appreciated... BAsically i have a 09 release core 2.8GHZ mac 15" antiglare. I had a dropping accident 2 weeks ago, which insurance have decided to pay for a new mac for me as opposed to repiar. However now the new chips have come out, I dont know where to go for the I5 or I7, i do a lot of video work so im thinking I7. But now with the antiglare the price has hiked quite a lot, if i have both I7 and antiglare... would i see much difference if I just bought the I5, next to my 2.8 . how do they compare ? is there an online comparison ?
