What would happen if you tried to run a super demanding game at max specs on those settings?

I imagine if the game loaded at all (it might check for certain features that'd be missing) it would run at about 2 FPS and make the computer really hot.

You can run to the store and buy a new rig!

Just try some games you have, it’s usually better than you expect. I can play Anno 1800 on my PC for quite a while which is specced far under the minimum requirements just fine, until my town gets too big in the late game, before it chokes. On my laptop it runs much better at decent graphic levels because my laptop’s CPU wipes the floor with my desktop’s CPU (which isn’t much better than your’s actually), even though that one’s still only barely powerful enough. You should just live on the edge a little.

Small indie titles, and some MMO's.

Any game made 7th gen and earlier is pretty much a guarantee. (I.E. 2013 and earlier.)

Later games like Ori are possible.

Your GPU though is based on Fermi, but only has 96 Cuda cores @ 625Mhz... Basically a slightly slower desktop Geforce GT 430/530. - Jump on Youtube and see what games that GPU can run and you should get a similar experience maybe with a setting or two reduced.

Your CPU is a Dual-Core Broadwell @ 2.7ghz, games like Battlefield 3 will be okay on that, but load up something like Civilization and it's limitations will become readily apparent.
