thats a good computer you got there. above average if you ask me. i am like the only one who owns a 6800gt in my whole computer program in college. hell probably even half of the college, i am the only one with a 16 pipe card. and my college is pretty HUGE.
i dont know anyone else who owns a 16 pipe card, or close to one. yet i still wish i had a 7800gtx....
overclock that venice you got. my amd 64 winchester 3200 socket 939 is at 2400mhz (default is 2000mhz). it can do 2600mhz with 1.650 volts with perfect stability. AND MAKE SURE YOU CPU TEMP NEVER GOES ABOVE 60c WHEN INCREASING THE VOLTAGE.
