All the info you need for SLi.

No..
Obviously the ATi cards can't do SLi. The GeForce 6200 can't either, but the GeForce cards 6600GT and up can.

I'm not sure if the regular 6600 can.

Some 6600's can, I've seen a few. But why?...

ok, thanks for the info, thats exactly what i needed to see

looking at this x 2, hope would be that this would be a great gaming rig for about 16 months before the next upgrade

If you only need them for 16 months, just get one.
