I earned about 500 000 tc without spending a peso on Toribash. Moreover, I earned 50$ with this game. Win tourneys, trade items, draw textures with new graphics card,that's much more exciting than buying virtual goods for real money.
If your buying a graphics card you need the right specs to use it. You cant just go out and buy a GeForce 8 series and shove it in th board and expect it to work.
