New system advice...

I've just bought and built a new pc consisting of:

Asus A7N6X Deluxe m/b
AMD Athlon 2500 Barton cpu with AMD fan and heatsink
Antec case and 340w psu
512Mb Crucial pc2700 DDR ram (2 x 256Mb)
Maxtor Diamond max 120Gb SATA h/d
ATI Radeon 9600 Pro AGP card 128mb
Windoze XP os

I'd like to know how far I can probably overclock/overbus this system?

I also have 3 extra fans in the case (one top rear, one bottom front, and
one in side panel opposite AGP card) to keep cooling under control, so
ventilation shouldn't be a problem.

My system is currently running at the default 2500, but what changes to
the bios settings do you recommend.

Eg: what clock frequency should I set?
what memory settings?
what core voltage?
what AGP aperture size?

Etc, etc...

I have already d/l'd and installed the utilities (Radlinker) to overclock
the ATI card, and its running nicely.

I've installed Win XP and Directx9 and thats running smoothly too.

BTW, I've built and overclocked my last two systems, so I'm not
inexperienced or afraid to push the system a bit...

8-)

Any advice would be appreciated, thanx...
