Bitcoin Core extremely high syncing time I'm running Bitcoin Core wallet on a gaming PC with a GTX 750ti, and 3.7ghz quadcore processor, and 16gb of ram. My internet download speed is 15 116mbps via hardwire.

But for some reason the syncing is stuck on 2 years and 33 weeks. I just ordered 100$ worth of bitcoin (which should come in 7 days) and I'm worried that it won't go through if it's still syncing.

Does anyone know what I could do to fix this? It's making me anxious.
The transaction will go through whether Bitcoin Core is done syncing or not, so don't worry about that.  You just won't see the transaction appear in the application until syncing is finished.

The Bitcoin Core GUI doesn't always give the most accurate updates on its progress.  But one way to check the progress is to open Help:Debug Window, click the Console tab, and type getinfo.  Look at the blocks number.  Then try getinfo again a minute or two later and see if the blocks number has increased.  If so, you are in fact syncing and just have to be patient.  Note that you are downloading about 60 GB of data and performing fairly intensive computations on all of it.

If you get tired of waiting, you might prefer a "thin" client that doesn't try to download and verify the entire block chain.  See Cannot access my bitcoins because my wallet is still synchronising. What can I do to spend them immediately? to learn about your options for switching.
