Price Check 6800le with unlocked pipes and decent cooling.

I have an AGP 128mb Leadtek 6800le (nvidia card obv) which i am considering selling but i dont know what its really worth.

It has a large copper heatsick as standard. I have modded the bios slightly so that all 16, 6 pipelines are unlocked and so that the fan runs more slowly and is very quiet (about 2 degrees warmer but so much quieter).

It clocks reasonable well but i tend to run it at stock anyway. It has its original box, cables, manual and it came with 2 games.

Any idea on what its worth?
