Questions: I have enough parts on hand to build a folding machine using a GTX260 and a Intel 2.66 dual core. I will be using GPU2 on this machine (although I'm using GPU3 beta on my 470). This will be for folding only 24/7. 1. XP or Win7? (if XP do I install all the service packs?) 2. Antivirus program (Yes or NO)? 3. Anything I can do to maximize scoring? 4. What version should I install? (I usually use system tray) 5. Should I fold both CPU and GPU? system (if needed) p-45 chipset, 4 gig ram, one old 36gig raptor (sata),550watt PSU This will be an open air system (no case). Also this is a factory OC'ed card can or should I go back to stock timing with Afterburner or should I use Riva Turner?
