Thanks for all the replies.
Haha, you think my GT430 is wimpy? My other graphics card is Radeon 3450M... now THAT is wimpy!
I have noticed when playing Lord of the Rings Online that when I get into a town it doesn't matter how low I set the graphics, I still get FPS of less than 25 max. So I guess that must be CPU getting overloaded.
I have high hopes of picking up an obsolete Core 2 Quad for nothing from my work. I'll stick a Radeon 7750 in it... It'll be a beast
