I'm throwing together some old parts to make another computer for the kids to play Minecraft. I think the Gigabyte GT 7600 is better than the G3258 but I'm not sure. I'm having trouble tracking down what version of Intel graphics is on the chip. If it is just Intel HD then the GT 7600 would be a step up I think. The integrated worked ok for Minecraft but a racing game she was trying to play was lagging. If they GT 7600 is not much of an improvement, any recommended cheap video cards? Thanks
