I currently have a Mac Pro from 2009. It works like new, 12Gb ECC RAM, Radeon 5870 HD Graphics, 4 Core 2.93 XEON. It's good, but when I use Final Cut X, rendering a 10 min HD Video can take a 2-3 hours. I thought about upgrading the 4 RAID HDD's to SSD, but I have upgraded this computer a few times now. Ready for something faster. I am thinking about the Mac Pro 3.7 4-Core, 1 Tb SSD with dual D700. Then I see the late 2013 iMac 27in 3.5 I7, 1 Tb SSD with the GTX 780M graphics. They are about $1,400 difference (I have a Cinema 30in Display, so I would not need to buy for for the Pro, but the iMac appears to have a better monitor). I am not certain I care about the price difference, I just want a good machine. I do not use my Mac for work (I must use a PC, company policy). I will only use a Mac for home. My hobby and passion is Photography (Lightroom & Photoshop) and HD Video using Final Cut Pro X (I don't care for iMovie). I like to make qaulity short films for personal use. Family and friends always ask me to create their wedding and other important videos. I do that 60% of my time, my other 40% of the time I game in boot camp as the games run much better on the Windows side (I would prefer that not be the case). So quality and speed is important. I keep my machines 4 years, I see my Mac is worth basically nothing now. So I may upgrade every 2-3 years now. I can't decide which to get, HELP. I want the Quad Core only because it's faster for 4 core use, (so gaming and Adobe products). I am uneasy about the iMac using laptop hardware, perhaps I am prejudice but I feel like it's fast like a race car but without power to pull a heavy trailer. The Mac Pro may not be as fast, but it can pull the heavy trailer (meaning Final Cut Pro, filters, rendering etc). I wonder if I will miss ECC RAM, probably not as non ECC RAM is stable today without the 5-10% slowdown. Because the Mac Pro has dual D700, I doubt they are used together, I believe they are more used as 1 for the monitor(s) and the other for heavy lifting if the software is designed for it like Final Cut X. For games I believe in most cases only 1 is used with the exception of Boot Camp where the driver may tie the 2 together. I know the iMac has Thunderbolt 1, Pro has TB2. Ughhh, I go back and forth. Just not sure which one will give me the best performance (I am not using 4k video, only 1080p as most folks don't have 4k televisions I know so no use in making them today for me). So I wonder if the Pro will be a lot faster for Final Cut X, and Gaming. Or if the iMac will be similar or same in speed. The Cinebench R15 scores are very similar for both 4 core systems that I have seen. However, both are nearly the same GPU bench speed as what I have today, both are close to 2X the CPU speed in the benchmark though. Sorry for the long post, I appreciate any insight or knowledge folks on here may be willing to share.
