Was going to say that I don't get any CTD's on my new machine, but I was just rewarded with a "nice" CTD after defeating 2000 men Arverni army near Ankira on my KH campaign, while losing only 350out of 1100 men. It didn't even happen immediately after battle as another AI faction was already in the middle of its turn. That was actually only my 1st or 2nd CTD on the new computer (and what a great timing).

On the old PC I was getting CTDs quite regularly, but it was P4 with 1Gb of RAM and ATI 9250 video card. EB was rather stressful for that PC. New PC is AMD X2 4800 CPU, 2Gb of RAM and 8800 GT graphics card, so hardware specs are surely not the reason this time.
