Using a custom BIOS for the HD3870?

[alf717]

I have two Visiontek 3870's one is a regular 3870 and the other is the OC model. I wanted to try and over clock them as far as possible on air cooling. One Visiontek has the Accelero S1 rev2 and the over has the standard cooler installed.

My search led me to the following BIOS and flashing utilities:

Would the following tools be a good start to help flash my cards? Is the following BIOS a good choice? I understand the risks I take by doing this but I want to educate myself before I do something wrong and mess up my cards.

Below are my video card specs via gpu-z 0.2.3.
