Looks to me like the X1800 will be a good competitor to the 7800, and with the CrossFire cards for the X1000 series they'll be to breach the 1600x1200 resolution limit.
Sorry if this was already posted elsewhere. :unsure:

I fully agree, great competition, but 60Hz @ 1600x1200?

The X1800XT has a very efficient architecture, and even though it has 16 pixel shaders and the GF 7800 GTX has 24 it overcomes this limitation with a much higher clockspeed and more than 10GB/s greater memory bandwidth. The theoretical raw fillrate on this thing is insane. Furthermore, it seems to have a much more effective implementation of SM3.0 than the 7800 GTX. As is usual with ATI, their D3D driver performance is exemplary and their OpenGL driver performance is utter garbage. I cannot emphasize enough how big the pile of crap is, that is ATI's OpenGL driver. But in D3D the X1800XT is considerably faster than the 7800 GTX.
Overall, it's one heck of a fast card. It is not, however, scheduled to be available in quantity until 11/5, which gives Nvidia a window to make that 7800 Ultra we know is up their sleeves. Nvidia will need to significantly increase their memory clocking, as right now it is well short of what the X1800 has. I don't know enough about SM3.0 to comprehend what ATI has done which causes the X1800 to outclass the 7800 GTX to the degree it does, but whatever they did, it's very impressive. Nvidia has a lot of catching up to do, again, though the performance deficit they need to overcome in SM3.0 isn't nearly as huge as the problems NV30's SM2.0 had versus R300.
There still things like overclockability, price, noise levels, power consumption, and cooling to take into consideration. The X1800XT does consume more power then the 7800GTX (25W more), uses a two slot cooler and has higher noise levels. I have no idea about overclocakbility and even though the price right now for the X1800 XT is high it will most likely fall.
