Mr. MinisterofDOOM,
that pc first of all is not monster at all. It is just high end parts stacked together.
Try 3.2ghz P4 overclocked to 4Ghz and geforce 5950 overclocked to 550mhz with 56.72 drivers. Liquid cooling does the trick i say.
Oh, I can push Pentium 4 a little more than 4ghz---couple ice cubes in water tank work magic. LOL
==============================================ABOUT DOOM 3
best dynamic lights, shadows, best light rendering across textures, skin, etc... best ever, but
texture quality sucks, gameplay sucks big time, sooo boring..
yes it is good when u start playing it, but it gets so boring, cheap fear factor techniques.
Halo multiplayer(PC) is still fun and my favorite.
If u haven't played pre-doom titles, then DOOM 3 is just looks good, very good, but not fun to play at all. It is like Unreal 2. looks real good, but gameplay sucks.
with my pc specs, i get about 40-60+fps in medium environments/ high settings/everything turned on/ 1280x1024 res/w/21" monitor/audigy2 zs/7.1 s750 speakers.... whole nine yards.
ultra looks same but runs abt 20fps/not playable.
so there.
I really hope we gonna have some good modes made for doom 3 soon. try duck tape mode for now.
hopefully HL2 is gonna be fun and make my day.

really hope. other than that, this high tech world is very boring, dont u agree. evolution moves very slow.
