I just bought a new C-Dale R600 and when riding up hills or really putting force on the cranks in low gears, my cranks creak and sometimes rub against the front derailleur. Thinking about switching and maybe getting a crankset (Campy Record). Would this solve my problem?

You could also go back to the shop and see if an adjustment needs to be made now that you have been riding awhile on the new bike. Could be a little less expensive than a new grouppo.

If new,I'd take it back to where you bought it.If the crank/BB is really at fault and it is not something fixable,a 105 or ultegra would be more in line with componentry on the bike,unlikely to flex and alot cheaper than Record.

Why not just start with tightening your crank bolts before you swap them out? That's most likely the cause of the creaking. All it takes is a wrench and some effort... much easier and cheaper than replacing things because the bolts aren't tight enough.

If he's been riding it with looss crankarms,they may be trashed anyway.

True.... I just though it would make sense to tell someone to check the simple stuff first before assuming the worst.

I have a new R-2000. I noticed a creak in the left crank, which turns counter to the crank bolt. The right pedal of course turns with the bolt. When I checked, the bolt was very loose but not so much that the pedal moved around. And it never made noise uphill when the crank was stressed.

I tightened the bolt the first time in 95 degree heat - bad move - cause it happened again the next ride, but not as severe. When you go to fix it let the metal cool and then tighten the bolts. Aluminum expands a huge amount when it is warm and you won't torque it enough.

It seems silly that the threads are set up counter to the rotation of the pedal. Your cranks must have been very loose to hit the derailleur. How in the world did you pedal?
