Hard to know, games are getting more VRAM hungry lately, if you want it to last that long get at least a 4GB video card. There is also no PSU listed, thats not a trivial component, you should list it too.
It's a pre-built gaming pc which comes with a Raidmax Vortex V5 casing and a 450W PSU. Must be a FSP Hexa+ 450.
It's a budget PC, so I think they have installed an average quality PSU.
