My 2007 imac died and I'm in need of getting a new computer. I'm down to two refurbished choices : 3.2ghz 1tb HDD at $1529 or 3.2ghz 512 flash storage at $1949 Imac will be mostly used for Lightroom 5, PS, and some cubase/kontakt . I want this computer to last me for about 5 years and I'm wondering if the extra $500(including tax) for flash storage even makes sense. Any advice? Thanks!
