Answer by expertgamerman
both these comps are basically the same not much differences but the first one has the slight edge on processor but the other one has slight edge on graphics so go for the second one also both these rams are the same just one adds that it has 2 dimms meaning 2 slots and if it says 4 gb shared it means 2 x 2gb so both the same its better to have 2 2gb than 1 4gb due to speeds and the whole meaning of ddr (double data rate) so go for the second but not really any difference both good so have fun :)
