So, I got a deal on the table for a Vanilla GTX260 for $145 shipped. Adding this to my main gaming rig would be ideal or I could eventually toss it in my "htpc" machine.
Although, adding this to my main gaming computer I would have to upgrade my power supply as the 1k watt psu's I had were on loan

. My current psu is a Corsair CMPSU-750TX. So would it be worth it to add another GTX260 and get another PSU?
I would also have to remove my x-fi since I would not have any open pci slots by adding a new card.
