advice with dedicated physx card & possible sli

[PubZombie]

Hi All,
I currently use an nvidia 460 as my main gpu and I am thinking of using my old nvidia 260 as a dedicated physx card. I was wondering if this was possible as the 460 is DX11 and the 260DX10 - will this limit my system to DX10 only?
Also I have the opertunity to grab another identical 460 at a very good price and could go SLI. However, I am wondering if this is worth it as I only use a 22inch monitor - I do however do a lot of 3d gaming as the monitor is the samsung syncmaster and I use 3d stereoscopic vision.
thanks in advance for your help and advice

It will work fine and won't limit you main card in any way.

Another 460?....with a 22" a single 460 is still fine.....I am sure it won't be too long before it starts showing some cracks but 2 x 460 + 260 is going to need a hefty PSU.

Would be better to sell the 460 and trade-up when you need to.
