Thank you for viewing this thread, this message is a little long so skip to the end for a condensed version. Hey, first time poster and long time lurker. I've been looking at purchasing a used 2009 Mac Pro (4,1) to replace my 2012 Mac Mini (i7). While I love my Mac Mini I've ran into an issue when using a new monitor I purchased, when running it in 3440x1440 resolution I get a lot of strange artefacts. Something which is common with this Mac Mini. Currently my Mac Mini is a quad-core i7-3616QM 2.3GHz with 16GB 1600MHz memory and the original 1TB HDD. The closest Mac Mini sold today is a dual-core i7-4578 3.0GHz with 16GB memory and costs £1,119/~$1,590. I would hate to pay out this much money on something I feel is inferior to what I currently have. So looking around the usual places I've seen that I could get around £650/~$920 for my current Mini if I'm lucky. For that price I've seen a number of 2009 Mac Pros, often quad-core Xeon 2.66GHz processors with 12GB 1066MHz memory, 1-3TB HDD (often paired with a 250GB SSD) and often either a Radeon HD 7750 1GB or what I believe is the original NVIDIA GT120 256MB graphics card. Would these machines perform better than my current Mac Mini? I don't mind spending money on them in the future to add more memory etc. I believe that I could add a hexa-core processor and faster memory with a firmware update in the future? I don't have much experience with Mac Pros (in-fact the last "Pro" desktop Mac I used with a Power Mac G4 around 15 years ago) and don't know how the Xeon actually performs. I typically use my Mac Mini for: General day-to-day browsing, checking emails, downloading photos from my camera and listening to music. Light Adobe CC use in Photoshop CC, Premiere CC and After Effects CC. Capturing video footage using a USB 2.0 capture device from old analog devices (VHS etc.) Playing the occasional game in Windows (currently through Boot Camp on my Mac Mini), typically these games are Windows Store apps such as Minion Rush, although I do occasionally play a bit of Civilisation: Beyond Earth. Currently my Mac Mini handles these tasks without an issue, and the only reason I'm even considering the change is because the screen artefacts are starting to annoy me too much. I'd just hate to swap out my Mac Mini for another machine and find it performs poorly. Conclusion I'm looking to replace my Mac Mini 2012 (quad-core i7 with 16GB memory) with a 2009 Mac Pro (quad-core Xeon) and was wondering if I would notice any performance decrease for web use, Adobe CC use and booting into Windows 10 for casual game titles such as Civilisation and Windows store apps. If I'm lucky I should be able to get around £650/~$920 for my Mac Mini, and for a similar price can pick up a used Mac Pro 4,1. I wouldn't mind upgrading the Mac Pro in the future as my Mac Mini has gone as far as it could ever go (other than a SSD/HDD upgrade). Does anyone thing this a wise upgrade choice? Do you have any other suggestions? Again I know this message is rather long, especially for my first post, but I would really appreciate any thoughts you all might have.
