Hey 21...here are my PC's specs (totally overkill for UT I think)

Nice setup.  I7 and 460 card with fast clocking and ddr5 memory. I wonder how much faster you play than me.  What I mean is, I wonder if you see me before I see you and maybe you're not in the spot I see you when I shoot?  I never seem to hit you, even when I aim ahead of you.

Thanks!

i would have to say no, the running specs for this game are 233mhz and ram something incredibly low 128mb ???? They specs would rise considerably with massive sniper maps and monster hunt plus AA/AF enabled. In fact some hi spec modern machines actually can cause problems with UT not recognizing multiple cpu cores and quiet and cool plus speed step setup in the computer bios.  Although now written out of several previous patches this game is built around Glide renderer and dx 6/7. There is no advantage to be gained with excessive machine specs unless you are using a monster size display screen.
Ping rules supreme - i sometimes play on the European multiplay servers with a ping as low as 40 and occasionally Foreign players join with a ping of 200+ unless they are a UT masters and up against a noob there is a high chance their gonna lose. I play on the UT Demo 348 i am part of a American Clan and always play on US servers.

The comment above "I wonder if you see me before I see you and maybe you're not in the spot I see you when I shoot?  I never seem to hit you, even when I aim ahead of you". This applies totally to ping. Two players facing each other shoot at the exact same time one has a ping of 200 and one has a ping of 50 the higher ping will always lose, trufax. machine specs don't really come into play unless it really is an old dog on a max map.
I dont know the max figure anymore for map building and the number of polygons used but i do know if exceeded the map can error, run badly etc, this can happen regardless of machine spec and obviously worse on archaic machines.

Oh yeah my machine specs, i use a netbook with a 10inch screen, no cd drive. As for get up and go, i can just about get away with playing UT2007 but the frame rate drops heavy in 6+ rocket battles.
