your psu is not support for 2 card.Better if you can purchase new psu to be 850-900watt
if you need to use both card.
Main 460 and use 260 for physx dedicated.
But if you have more money i suggest you should use one card only such as 470 or 480
it very better for the game. but should be change psu also.
Sir. I have never had experience using dedicat nvidia card for physicX before... in this case will there be significant difference between GTX460 alone VS GTX460+260 ????????? how many percent difference do you think there will be ??????
