Actually, the older graphics do put a considerable load on systems as they tend to use graphics engines which are not as efficient as a modern one. If you REALLY want to oil your system, enable shadows. I did that and it really worked my system. I couldn't figure out why I'd get such bad lag when I saw large numbers of people etc. When I turned off my shadows, no issues at all..
As others have noted, this is quite likely a heat issue. Checking the BIOS settings and your fans will be a great start
