Why dont you stick with your current PC? (Unless its too slow)
You can always upgrade certain components.
A PC is much more functional than a Mac. Due to codecs differences, its probably better to get a PC in the world of video playing.
You might do some reading, here is a topic that has gone on and on on ComputerHope for a long time, a debate on whether or not a Mac is better than a PC:

A Mac is just as insecure and as capable as getting a virus as a PC. There are less virus programmers for the Macintosh operating system, since its a much less used system. Dont let the guys at your local Apple store trick you. Chances are, if you are used to using Windows, its going to be even harder to switch to the Mac OS. Compatibility with software and hardware is a huge issue with Apple computers, as they are so "closed up" and prevent users from being able to really start customizing their systems.
