EDIT: Should NOT be the iMac 4,2 in the title -- I'm referring to the late 2013 core i7 model. Like many, I have been reading the threads about the nMP. I was up late the night of the release but didn't pull the trigger on a base model figuring the CTO options would have the same build time in the morning; wrong! Anyway, I find myself considering something that I haven't before: an iMac. I wanted to ask the more informed about my situation and see what people think. Current situation: * MP3,1 2x2.8 with 8GB RAM running 10.8.5 (I tend to keep my desktop machines a long time) * 256 GB SSD (internal) for boot, apps * 4x1TB HD (internal) set up as a software RAID10 for data (1.2TB currently used), backed up to a 2TB Time Capsule * 500GB HD (internal) for Win7 via VM * ATI5870 * 27" LED ACD + 2x24" ACD (mostly just use one of those) * FW CF card reader (digital photo import) * FW Apogee Duet (audio import) I don't really do much with video, other than some minor home stuff. For photography (prosumer/hobby), I use RAW files from a Canon 1D (LR & PS, DW--though LR is generally the only program I keep current). I pretty much have to run at least one virtual machine (VMWare) with Win7 at all times (currently allocate 2 cores & 3GB RAM); not doing anything too intensive -- it is mostly for VNC/remote access to another server. I just need to keep things separate. The VM file is ~30GB. It's not terribly fast. Of the 1.2TB of data, perhaps 1/2 of that is video files that I've saved and sometimes serve to other devices I use (iPad, ATV, MBA). In the recent past, I have produced my (local) radio show using Audacity for recording vinyl and mixing. ====== I was considering the 6-core nMP with either 16 or 32GB RAM and the 1TB SSD. Not sure about D300 or D500. I thought this would be the sweet-spot for the processors. I was thinking that I could use the 1TB SSD partitioned as 256GB (startup & apps) and move most of the data I work with, along with my VM, to that. I was thinking I might notice a performance improvement. I could move 1 or 2 of my 1TB drives to some external enclosure to house the less frequently used video. (Have to buy some enclosure, but I guess that would be TB or USB3.) While I'm not rendering 4k video, I do value instantaneous response when browsing photo libraries, starting programs (sounds silly), etc. I'd consider ditching both 23" ACDs in favor of one 27" TB ACD. ===== Reading some threads I started to think that maybe an iMac (27" core i7 with 16 or 32GB RAM) could do the trick. They are more readily available. With a 1TB SSD I feel like it would probably be an upgrade over my MP. I think I could add a 2nd SSD in there. Since i have a track record of keeping machines for 3-5+ years, I have to confess that I'm a little worried about an all-in-one. For reference, I live 300 miles from the nearest Apple store. I'm VERY technical, but if something fails, there's not much one can do. When the 8800GT video card failed in my MP, it was obviously a trivial replacement, and the whole system kept on going just fine. Am I right to fear this? The nice part is I get the display, but I don't want to be short-sighted. ===== The MP is not exactly a slouch. I guess I could add more RAM, or buy a bigger SSD (or multiple SSDs), or upgrade to an ATI 7970 (probably not wise)...or drop in new processors... but I don't know if it is worth investing more time and money into it vs buying new. Any thoughts? Guess I could always order the nMP now to get in the queue and cancel in a week if I change my mind. I realize that this is not a desperate need. Part of me gets off on having the latest machine...I confess I like new toys. Thanks!
