Processor upgrade from Integra 9.8?

With arrival of new SOTA TV, will be going from 99% 2-channel to 85%. For 3-d capability, my question is whether to upgrade to Integra DHC-80.3/Onkyo PR-SC5508 or to go higher up the chain. Not sure what, if anything, I will be giving up by purchasing at the $2K price point vs $5K, other than, of course, an extra $3K of expense. Also have an Oppo BDP-95 on the way for Blue-Ray/3D. Will be incorporating front speakers, preamp and amps from 2-channel into the HT system.

Thanks for any help.
