Can I run apps off my PC via my Mac?

I already own Parallels but for graphic intensive games, I still use my PC. It's in my room here next to my mac, but I plan on putting it downstairs in the rec room soon.

Is there any way I can run applications (games) from my Vista based PC over my home network from my iMac? For example I want to play The Witcher. Could I put the disc in my vista pc in the rec room (or load up a disc image) and run the game, but interact and actually play it via my Mac? Think VNC for gaming.

My home network is a Dlink DGL-4300. Both systems are connected via wired gigabit ethernet. I have plans to upgrade to an Apple Airport Express soon, along with a gigabit switch to handle the wired overflow.

I wouldn't mind sitting infront of the PC for gaming but it has a 17" LCD display, which belittles in comparison to my iMac's 24" display. I figured if the lag wasn't too bad, this may be a cheaper alternative?

Short answer: yes. You can run Windows applications on your Mac via a mapped network drive.
Longer answer: yes, but there's little point in your example. If you primarily intend this for games, you'll be completely disappointed. Not only will you introduce (likely unacceptable) lag into your gaming experience, but you will also limit your gaming experience to the graphics capabilities of your laptop. There is really no point in having an application run on one computer and control it on another, unless it is a business application or something that is processor, but not graphics, intensive.
