Oh it's nothing special really, A radeon 4670 I think it is. but I am using an asus crosshair (gaming mboard) with an unimpressivee 5200+ and 4 gb of Geil low latency memory in 4 banks Yea I was so suprised myself when I check the frames. I could never get this on that apparition that microsoft came out with. On the same system with vista and fsx and all manner of tweaking I was lucky to get 20 frames, that was both at locked and unlocked modes. I think that the key to good frame rates is not so much your graphics card buy what is beyond it. Motherboard / processer / memory etc. Nice talking John
