1,000,000 limit is FIB which is only best routes(500K+ routes), RIB only consume RAM.
You'll be fine with 8Gb memory, but if you plan to use non-cisco memory, just go with 16Gb its cheap. 16Gb will be enough to store 25M routes as Route-Server last I heard from Cisco. IOSd will only consume half memory of available for platform. Regardless ISSU (which is need additional memory if enabled).
