I have a i7 2700k, 16 GB 1600 HyperX ram, 256 Samsung 830 SSD, etc., and 3 SLI'd 580's (moving from previous build) going onto a ASUS P8P67 (B3 rev.) mobo. I have a GTX 550 Ti lying around, and want to know if the motherboard is capable of using the 550 for PhysX with the SLI'd 580s, or is the board only capable of just the 3-way SLI? I would prefer to add the card as I am OCD and like my temps to be close to even when in SLI; however, without using a separate card for PhysX, there is always a card with a skewed higher temp as it performs double-duty. In any case, any answer to solve this will be appreciated. Slot description:

1) 2.0x16_1 slot (single at x16 or dual at x8/x8 mode)
2) 2.0x1_1 slot
3) 2.0x16_2 slot (x8 mode)
4) 2.0 x1_2 slot
5) 2.0x16_3 slot (single at x16 or dual at x8/x8 mode)
6) 2.0x1_3 slot
7) 2.0x16_4 slot (x8 mode)

***I am aware of the N200 chip, and I am aware of performance specs of various SLI and CrossfireX solutions. I also am very aware of what electronics cost, since it's my money that buys them. With that being noted, I am not here for opinions concerning frame-rates, cost/performance ratios, or in my overall wisdom in the choices I make. My apologies if a little blunt, but too many answers in these forums contain as much condescension, patronization, and sarcasm as they do helpful facts and polite advice. In any case, if anyone does have the answer and/or further information that could help, you have my most sincere gratitude. Thank you!! :)
