As a recreational rider, I'm pretty satisfied with my Giant OCR3 frame. I've been bit with the cycling bug pretty badly as I've already upgraded most of the components and wheelset over time. Only things that have remained stock are the cranks and bottom bracket.

Would it be worth it for me to upgrade from this frame to a Cannondale Six13 Team frameset? The stock cranks and bottom bracket are included in unused condition. I'd be going from full aluminum frame to mix of aluminum/carbon frame and alum crankset to bb30 carbon fiber crankset (I'm assuming this counts as a significant benefit). The cost to me would be less than $700.
