Hi guys, I'm new to the forums, infact this is my first post. Traditionally I've been a windows user and a hardcore gamer in the past but not anymore. Last year I invested in a Retina MBP after having more laptops I care to remember and I was blown away. It's stunning and hands down the best laptop I've ever owned and being an IT professional is a great dev environment (why it took me so long to realise this is beyond me). Anyway I am really interested in the new RiMac and it's more of a culture shift to me than anything. I have a few questions if you would be so kind. This is the current spec of my gaming rig, which I don't use much for the purpose it was intended these days. Plus it's a noisy beast. Current System Intel i7-2600K CPU @ 3.4Ghz 16GB RAM 256GB SSD NVidia GeForce GTX 580 Box standard high ms response time monitor These days my requirements are around browsing, media, casual gaming and dev work in Coda, Shell and an IDE. I am looking at the following spec of RiMac 4.0GHz Quad-core Intel Core i7 16GB 1600MHz DDR3 SDRAM AMD Radeon R9 M295X 4GB GDDR5 3TB Fusion Drive Questions: I already have a 12TB NAS and have no experience of a Fusion drive. I am torn between the 512GB SSD and the FD. How is the FD for using VMWare Fusion for some legacy windows apps. Which would be the best drive? How does the M295X compare to my current GeForce GTX 580? I'll get a slight performance boost with the CPU but I'm not sure on the GPU side? I have quite a lot of Outlook mail in PST format and also want to make a move to Apple Mail. Any free utilities people are aware of to convert to mbox format? I'm a bit loathed to pay for a utility Ill literally use once. I am hoping to move my current rig on and like I said its more about a complete culture move across to Mac and I realise I'll take a hit on gaming performance, which doesn't bother me in the slightest providing I can play the odd game in a decent resolution from time to time. Anyway, I've rambled on a bit haha. Hope people can answer the above and convince me I'm doing the right thing.
