I'm receiving a gtx 560 ti in a couple of days. I was wondering if I could leave my old 9800gtx+ in my system and run it in physx mode in sli with my new 560ti? I'm new to sli configurations and i've heard that only similar cards can run in sli but i've also heard of people using their old gpu for physx purposes.

Yes, you can use it for a Physics card. Only when running in true SLI do they have to be the exact same.

Seen on posts from other people across various sites that the 9800gtx+ will actually slow the 560ti down as it waits for the older card to process

In my opinion its not worth adding the 9800GTX+ as a Physx card. The 560ti will handle it just fine. The added heat, power and issues are not worth it.
The physx library of games is not that great , so physx will only really matter to you if you playing them.

You can't do SLI, but you can keep it installed as a dedicated PhysX card. The rule of thumb gain in performance you're likely to see is about 25% over just the single GTX 560 Ti doing all the work.

Of course, you will only see that benefit on those games that feature GPU PhysX, i.e. the Batman: Arkham games, Mafia 2, Metro 2033, Unreal Tournament 3, and a few others. The Batman games alone are worth keeping the card as a dedicated PhysX card.

The first question to ask is, what GPU accelerated PhysX games do you intend to play?

Good link, I haven't seen that list before. Most people post a link to the one which use the PhysX game engine, not the one for GPU accelerated PhysX.
