I have a like new max out 2012 rMBP (2.9/8/768, 3 yr Applecare, 25 cycles on battery) and am tempted to sell it (can get around $1900- $2,000 for it) to buy a new Haswell rMBP in the 2.6/8/512 configuration. Does anyone knows how does the Geekbench of rhe new Haswell I5 2.6ghz compares to my I7 2.9 ghz machine? I dont really need the extra 256gb SSD size right now so may accept such storage downgrade. Would such machine upgrade makes sense to you? I run regular Office software and use it for general Internet browsing, no gamming at all.
