so if I am making recordings using RB (or PT) will I really notice a difference if i record at 24bit 4800? any advice from the more experienced?

I'm using a new condenser mic to get better quality than the old dynamic one but as I'll eventually be making cds will the higher quality recording translate to better cds when the fileis resampled back to 16bit 44.1?

My usb audio interface will support almost any bit depth and sample rate. I just need some advice as to whether the experts out there thinks it's really worth recording at anything other than 16 bit 44.1.
