Help with choosing a new bike

Hi everyone! I am looking for a newer more fabulous bike and I was hoping to get some starting points here.

I currently have a 2007 QR Tequillo with Dura Ace and stock Easton wheels.

I have ridden this bike “as is” from my first spring through 4 Ironmans (3x IMC and 1x IMSTG)

I was fit onto the bike by a great bike fitter in the Seattle area and I am comfortable on the bike but I know that it is seeing a lot of wear and tear and I am ready for an upgrade.

I am a MOP…never going to qualify for Kona…but I enjoy the hell out of training.

I am a Mom to 5 kids who all eventually will need some college tuition so I cannot drop 10k on a new bike.

The frame is in good shape so I am wondering if I should just upgrade the groupset, wheels and aerobars or look into a newer mid-level bike.

I would appreciate any thoughts on this matter.

Thanks!

If you have a 7800 or 7900 groupset then I would keep it and just upgrade the frameset and wheels.
