thats awesome. should be a great card. i just got a new pc with a 9800 gt, which is like 2 steps down from the gx2', and i havent had any problems with it at all. ive been playing quake wars an stuff at the 1680x1050 reso. on full settings, with no problems. and the gt seems to stay nice and cool. at least, with just one.
Yeah it's nothing but 2 9800GT's stuck together, but it gives roughly the same performance of the $600 280's.
Actually $400 now, and still going down. http://www.newegg.com/Product/Product.aspx?Item=N82E16814261015
