Will this PC play Gmod on a multiplayer server without lag?

I'm planning on getting a new cheap pc so I can play Gmod without all the lag, so I've came across the Lenovo ThinkCentre M53. These are the specs.

-Intel celeron j1800 (2.41ghz)
-4 GB of DDR3
-500 GB HDD
-Intel HD Graphics (Doesn't say which)

So I just want to know if I can play Gmod in a multiplayer server, without horrible lag. And at what settings could I play it at?

Well… Look at your specs… A celeron processor… Not a duo 2 core, not an i3 / i5 / i7…

intel hd graphics… Even if it was an intel hd 2000 ( like from years ago ). You will struggle in that game…

The older P4 processor outperforms your celeron…

soo-o-o- sorry to say… I'd stay away from that game… You could try… But you will be on low low game settings and you might be disappointed.
