Hi, I'm running it on x64 Arch Linux using an Intel Q6600 (Core 2, 4x2.4GHz) and a Nvidia Geforce 8600 GT with 256 MB and propriatary Nvidia-driver. I'f done a RAM-upgrade a few days ago (2GB → 6GB) but that didn't really change something. If I don't get to many troops in a battle (200 vs 200 is good, but shouldn't get much more) it runs smoothly. I don't know, how much this will help you, but it propably gives you a list, that works OK.
