Recommendation for video stressing program for old laptops

[Caveman]

Gateway P-6860FX with 8800gts
Acer with 240M

Both laptops are approx 6 years old and have Windows 7 installed... I'm assuming a dx9 stress test is appropriate...

Just want to check loaded temp before and after TIM improvements

3DMark Vantage (those are both actually DX10 cards) or Furmark?
