Recently put in a GTX 560 and kept my 8800gt as a dedicated physx card. PSU is a PC Power and Cooling 610 Watt. 560 is hooked up with 1x6 pin and 1x6+2 pin. 8800 is hooked up with the 2x4 pin adapter to 6 pin. Using MSI Afterburner to adjust voltage and overclock. Force constant voltage is checked in Afterburner. No overclock is made to the 8800 GT.
Overclock with voltage mod does not work well, or rather, with stability in any game. Overclocking voltage to 1110 volts, from the standard 1012 volts, and raising my core clock to exactly 1ghz.
Overclock w/out voltage mod works for at least an hour in games like starcraft 2, crysis 2, or TF2. No overclock settings seem to work in physx games, however, (specifically metro 2033 and Batman AA) regardless of the voltage. Also, CPU is e6550 overclocked to 3.16 fully stable.
Is the PSU just not enough to add more voltage to the 560 and keep the 8800 GT on? The physx enhancements are pretty noticeable in Batman... but I already played the crap out of that game. Metro is pretty terrible, and with the lack of news on physx games, it seems like a good idea to just take out the 8800 and sell it. Oh well.
Any buyers? Make me an offer.
