Oh and keep in mid my comp is just a
9600 -GFX
4 gigs of ram
and a duo core 2.2 GHZ processor
You probably have a even better processor. I went through 4 video cards and lots of different amounts of ram so here is a quick review.
(all gfx cards nvidia)
5200 - 512 ram - 3.2 ghz processor : barley play able
6200 - 768 - 3.2 ghz processor : playable on low settings
8400 - 2 gigs of ram - 3.2 processor : playable on high
9600 - 4 gigs of ram - duo core 2.2 processor - Playable on very high.
Keep in mind these numbers are for battles with one on one fights. We even *crashed a 100,000$ server at school meant for editing computer animated movies with a full 4 armies on 4 battle. They all just seem to chrash when you have over 10,000 men pushing through a gate. 7 on 1 siege battles in a castle are doomed to failure.
* It just restarted itself, it's not like we broke it or anything.
