Trying to Build an All-Around Computer. (with a twist)

First off this will be MY first build but I have a couple of friends who have built rigs that will help me once I have my components.

I'm trying to build a PC that is both good for some gaming use as well as Solidworks. But here's the twist, I'd like all the components to be compatible with Apple OSX as well. (I want to run windows and OSX) (dont flame at me for this)

If its possible that is.



Budget: $1500-2000 (I dont want to be cheap but I dont want to spend all of it if I dont have to)

Case: dont have one picked out yet but I know I want a functional yet stylish case, size doesn't matter, this rig will be built and kept in one spot;

System Usage from Most to Least Important: gaming, Solidworks, HD video editing, graphical stuff (photoshop etc.)

Are you buying a monitor: No

Do you need to buy OS: yes, part of the budget if possible

Preferred Website(s) for Parts: newegg.com/amazon.com (willing to try others)

Country: USA

Parts Preferences: Whatever works best

Overclocking: if necessary

Your Monitor Resolution: 1080p

I'm open to any and all ideas/help.

I will probably be purchasing/building around mid September and would like to have a full list of components by then.

Thanks!
