Before you sell the 3rd 260, you can always try it out to see what you are or aren't missing.

Generally speaking, there are very few GPU accelerated PhyX titles. For the few games where you really need a dedicated physX card (dark void might be the only one, perhaps metro 2033), you can always disable SLI and use the 2nd 460 for physX.

I'm suprised that you didn't get a lower score with 3dmark vantage. It doesn't work the way you might think with that benchmark. When they test out physX, they do it without any graphics power being used. They test it independantly. If it was higher, it probably meant you left your 460's have physX on, so the demo just had a higher score due to standard deviation.

A dedicated physX card is only useful when you are both rending high quality graphics and doing phsyX at the same time.

it simply kept also the 260 you put it only manages the physX

I was just thinking the same thing but with a GTX xxx card used as physx coupled with 2x Sli GTX 470's. Wouldnt be a massive improvement. Just looking for something to invest into Computer wise as i have a good wage coming in soon.

Physx is a useful feature in about 5 games. Unless you plan on playing those 5 games a LOT there is no reason to have a dedicated physx card.
