yea im happy with my machine. it costed me (with the 500 vid card) about 1700 bucks. I figured it compares with a 5000 dollar alienware, and i built it my self so it was way worth the time and effort. I just wish the videocard came in when i originally ordered it on 06-22-04.
About the fourth test. Nvidia uses 16/32 bit and ati uses 24 bit. from what i heard all the tests in 3dmark2003 run at the 32 bit precision where ati cards are only running 24 bit. Since test # 4 (nature) is the most taxing test it really starts to hurt the 6800 ultra. Thats one of the problems with 3dmark2003 being a synthetic bench and all. Now most games on the other hand use a combination of 16/32. they use 16 bit where they gain performance but dont lose Image quality. and use 32 where image quality would be sacrificed if they used 16. This is why all 6800 series cards do bad compared to ati cards in test 4.
The good news is 3dmark2004 will be out shortly (i hope) and when it is released im pretty sure it will do it in 16/32 mode.
