Ok, I know there are threads on similar things, but I need some guidance. For reference, I'm currently using a Mid-2011 MBA with 1.7 Intel Core i5, 4GB 1300mhz DDR3 R and Intel HD Graphics 3000 384MB. I don't do video or photo editing, gaming etc. I LOVE the quiet operation of my MBA and quick speed of the 128GB SSD I have. I hate the sound of fans or components running in an otherwise quiet room. I have to admit, managing the space (currently have about 20 GB free) gets annoying at times. I'm mostly doing web browsing, viewing/tweaking (but not full-on Photoshopping) pictures, listening to iTunes music or watching iTunes movies and streaming downloaded video content from my MBA to my tv via Air Play on my Apple TV. I've decided on the 21.5" iMac, but I can't decide (mainly because I'm not educated enough) between choosing between two possible sets of upgrades: Should I go wight the 256 SSD or the 1TB Fusion hard drive? Regardless of which option I choose, I think I'm going to finally purchase an external HD to back up my important or sentimental data. My initial instinct is to go with the 256 SSD because I'll have an external HD anyways and because I've read some "complaints" about the noise when the HDD is running on the Fusion drive. Due to the performance, lack of noise and dependability of the SSD, I've pretty much eliminated the 1TB 5400RPM HD, unless someone can give a compelling argument for it. Should I spring for upping the RAM from 8 to 16GB, or would that money be better spent on upgrading the i5 from the 2.7 to 2.9 GHz? Which one of these would be a more noticeable benefit for an user of my type? Also, which of the two would help delay the want/need to upgrade to a new iMac down the line? Because of my budget, I can't do more than 2 of these 4 (well, technically 3 since I can't have both HD options at the same time). What advice do you all have for someone in my scenario? Thank you in advance.
