Possible that a core dies?

Is there any possibility that a core could die within a laptop? I have the 2008 MacBook Pro with the Core 2 Duo, and i have noticed that as of late, when i do video production and handbrake encodings, it takes 2x as long as what it used to months ago. Like a handbrake encode went from taking an hour to two and half, or a premiere pro encode takes 6 hours for a 1080p 30minute video. Now i did downgrade from Lion to Snow LEopard since i was having GPU issues, which i think has extended into SL now since Starcraft 3 doesn't play at High like it used to, now it can't go past Medium. So, any idea what could have caused this slowdown?-Matt

Download Cinebench 11.5:
MAXON | 3D FOR THE REAL WORLD: CINEBENCH
...and run the cpu test. If it shows only 1 core working...then you have a "dead core". If it shows 2 cores working at the same time...then the slow down is something else.

My experience with dead cores may lie more with Powermac G5's & Mac Pro's...which have multiple cpu's:
- Powermac G5's...two cpu's (one cpu could be dead) leaving one working cpu
- 8-core Mac Pro...two cpu's (one cpu could be dead) leaving one working cpu (4-cores)
I agree...I don't think that I've run across a Core 2 Duo or a quad-core i5 or i7 (a single cpu setup)...that had an individual dead core.
