advice needed

I have a allez 16 frame that i was using as a training bike/ winter etc.Due to a bad mechanical at weekend Ive decided to change the groupset, I have a full sram rival groupset that i was going to put on. But now im thinking, should i just buy a better frame to put it on? the rival costs more than the frame and wheels (model b,s)! Have been looking at the carbon frame at planet x for 400£ , so should i put the rival on the winter hack or buy a better frame to put it on?
