I have a gtx 650 ti and a gtx 460. was wondering if it is possible to crossfire them and will there be any benefit? The 460 is just kickin around in a box and was wondering if I could make it usefull again.
No. In order to use SLI (Nividia version of CF), the cards have to have the same GPU. The 650 uses the GK107 GPU while the 460 uses the GF104. Incompatible.
