I have always been a PC owner, so if I choose to get a Mac, it will be my first. I am an avid gamer, and mostly play Blizzard games. But I would use Parallels so that I have the best of both worlds. Through the research I have done, it seems that the Mac Pro is generally used for people that do video editing and so forth, and your general iMac is just a general computer.
I am curious what would be my best fit, I want to play my games on the best settings and dont mind spending a few bucks if necessary. The comparable PCs I have looked at, have been comparable pricewise to the Mac Pro I configured. I am also not sure if an iMac can even be upgraded, ie...Video Cards, Ram, etc. Whereas the Pro is.
This will be something that I want to have for 3-4 years without having to purchase another computer.
I look forward to all your suggestions, and thank you for taking the time to help me out
