Is this a good gaming setup

I have no idea

ok

I.......ummmmmm...yes?

my setup is similar, Intel Core 2 Duo E8400 3.3 GHz and nVIDIA G92 9800 GT 512 MB and everything works pretty well, got this setup for 5 years now

nononononononononononononono bad deal

It's a fine computer but not for $500

Terrible deal and video card is ancient.

Ohhh, I can not deny the amazing moments I had with my old 9800 GTX+. She still works, but she is retired now, safe in my closet.

That setup, well, could be enough for most low-end gamers, to play light games, like the ones from Valve, Portal 2, Dota 2, L4D2... and stuff in this level.

But 500 U$ for it is WAYYYYYYYY TOOOO MUCH. I dont think you can even find this pieces as "Never-used". I could sell you my similar old rig for $200 and would feel bad for ripping you off.
