I was just wondering if anyone has tried it before and whether or not there were any problems.
I'm building a gaming PC with a friend which I want to use for video editing as well. The editor I use is Final Cut Pro which only works on the OS X operating system, so I was hoping to see if I can get a dual operating system happening so I wouldn't have to buy new editing software. (Which is really expensive!).
Does anyone have any experience with this kind of thing?

Quickest and easiest way would be to install it in a VM. VMWare supports OSX and you can use VMWare Player for free.

@thermite Thanks, I'll look into it. Hopefully it's not too complicated.

@tspec I've never heard of VMWare. I'll look into that too. Cheers!

For editing and gaming the video performance of VMWare might be unacceptable.

Yeah, I wouldn't use VMWare for gaming I assumed from the OP gaming would probably be done on the Windows OS, video editing is probably a little more suck it and see, if the host PC has a decent CPU and RAM, you can allocate more resources to the VM though it depends how intensive the video editing is, an ssd would also be ideal. I've done some basic video editing on a VM and it was fine but we're only talking snipping bits out of larger videos though this was a windows VM, not OSX.

I suppose the gaming would just be in windows.

I think the best solution is to change video editing software to a windows one. I know it's hard when you've gotten used to a particular program, but Adobe Premiere is quite similar to Final Cut, as is Avid Media Composer (Avid is the industry standard). There are also many editors available for Windows which are easier to use than all of those popular ones, such as Sony Vegas.

why not buy a mac and use bootcamp for games?

i thought mac OS X only supported PC hardware now

(being that mac hardware is long dead and unsupported)

i do vaguely remember apple coming down hard on some peeps running apple OS's on non apple products tho,

I thought you needed to hack osx to make it run on a vm

I checked into VMware and it seems that a lot of people struggle to get FCP to work well with it, so I think I might just pass on that idea. I forsee too many headaches.
The hackintosh idea sounds like a good one, but I don't think I'm computer savvy enough to pull it off. =(
Again, I forsee headaches.

I'm seriously considering just biting the bullet and getting Premier Pro. At least I know it will work and I wont be tormented by random issues I have no idea how to deal with.
