Friend bought a 2nd hand PC with good specs for her son, on good faith it was all working etc.....  unfortunately system is completely fried (mobo boots at random, video card dead, one drive dead).

So I'm trying to build up something on the cheap for her so her son can have something Xmas day,but need a basic video card that will run Roblox?minecraft.

Anyone have anything they'll let go for cheap that I can pickup tomorrow ?

TIA
