This is a fairly low-end machine as far as i can tell. The fact it has a giant screen and quite high ram for the price and the fairly premium feature of HDMI actually makes me especially dubious about gaming capability. Also with that Massive screen and, as far as i can tell, not Full
HD. Its all gonna look squat and stretched.
Also the processor is not dual or quad core apparently which
AFAIK would mean certain games would just flat out not run. EDIT: Forget that, i think it has 4 cores.
Another fact is that although Intel
HD graphics have improved ALOT over the years that is still just the base one and not
HD 3000 or 4000.
My Laptop has
HD 4000 and can run certain games pretty well, I get a decent frame rate out of Torchlight 2 and Path of Exile in fairly high resolution but some games really struggle. A game that Runs and Looks like utter Garbage on my machine is Dota 2 and guess what? That's a Source engine game, just like Left 4 Dead and Garry's Mod.
EDIT:
IIRC Source games are just not something you can play with any fidelity on integrated graphics.
I'm afraid
PC gaming at even a modest level requires a decent investment. I would do a bit more research.
This is a good little explanation of the graphics in your machine, it has a list of games at the bottom. (Alot of the page could be written in hieroglyphs but it still paints a clear picture):
