It will play new games at low/medium settings. Things like runescape should run much higher. The GPU is lower end and not really cut out for things like crysis or metro 2033. Those kinds of games will run at low/med maybe. BF3 might see medium settings and SC2 will see medium settings for sure.
Im almost scared to see what no name brand of power supply they dropped in it. When you get it look up the power supply here http://www.eggxpert.com/forums/thread/323050.aspx if its a tier do as the link suggests and replace it asap, preferably with something tier 3 or higher. They only way they could have made any money selling that thing would be to use the absolute cheapest parts they could find, probably what many items are missing the make and model. Be afraid be very afraid.
