Here is some info on what each of these settings does:

PCI Write/Read: These features allow the PCI Graphics card to write/read to system memory (As opposed to Video memory).

AGP Write/Read: These features allow the AGP Graphics card to write/read to system memory (As opposed to Video memory).

Fast Write: Fast writes allows the CPU to send data to the Graphics card without having to go through RAM, making it a far more optimal approach. That said in reality most benchmarks done on this have shown it to be of little actual benefit, in some cases performing slower, not mention on other systems it causes stability problems. As a result you might want to run a few benchmarks before choosing whether or not to leave this On or Off. On some systems this can cause stability problems & where it does you should set Off.

You can also use SMARTGART to auto detect the settings and set them for you. Also the reason you have the AGP Write disabled is because the Fast Write is enabled, you cant have both enable at the same time. To me your settings are just fine as long as your system is stable. If you start having some issues you can try turning off the Fast Write and using the AGP Write option. It will lower your fps, but not significant.

The best way to find out is to disable the Fast Write and turn on the AGP Write and see if you can play the game for a longer period, also if that doesn't work can you consider a heat issue maybe?

They are both essentially the same except the catalyst control centre is a newer version of the original ati control panel.
