Install XP and secure it thru SP3 for each system that can run an 8800 video card. The NVidia GPU will get you the most points.
Otherwise drop a Linux distro on them. I am not much help in Linux, and my son (Linux guru) has just moved off to college. We have several Linux pros around that can help.
Make sure that you use the same name and team number (36120) for every box. Please use your FReepname if you can.
For the systems that have an 8800, check the NVidia chart above and see where those cards place. Then move the cards to a quad core if possible, and dedicate a core to the cards. It takes one core to feed a GPU.
Look here for a new GPU installer that is beta but solves a few problems:

For this month just get an 8800 running in each system. Dual GPU systems can wait for next month.
Once each system has a working GPU, then count the cores left over.
If you have any quad cores install the latest 6.xx SMP code from the main Download page.
For every dual core then install the 6.2x console version onto that system, into the folder F@H1.
Important notes:
You need to install each F@H package into its own folder. I use F@H 1, F@H 2, F@H SMP and F@H GPU.
ALWAYS select Advanced options when asked. On most other questions you can accept the default.
Set the “Accept Advanced Methods” to “y”.
Make sure that you keep a pattern to each box and which Machine ID that you assign them. I always set my GPUs to ID 4, and then console 1, console 2 etc to match the name of the folder.
Do not forget your FReepname and team 36120.
I will heartily recommend that you install the script from Egon in his above post. Works wonders.
Much misery and wasted time otherwise.
Please ping for questions.
