Yup Well I just ran the game like a dream on a...

500mhz P3
192mb ram
64 MB Radeon 9000

With everything turned down, BUT THE GAME IS STILL EYE CANDY!

Which is way under miniums, Even when I'm zoomed in on 100-200 units fighting, No lag.
This is great, This is great, this is great.
Oh man I was so worried.
