I have ordered a dell vostro 3458 with i7 5500u, on-board Intel 5500 graphics, 4gb ram, 500 GB HDD. I have chosen this configuration over a similar priced HP laptop that has i5 6200u and Intel HD 520, 4gb ram.
I only do very little casual gaming (Minecraft probably), but I intend to use AutoCAD and Android studio. I got a one year exta warranty and the dell is 14 inches compared to the HP's 15.6 (which I like).
Would I suffer because of the low performance on-board graphics of dell in comparison to the 6th gen i5, graphics of the HP? I have time to cancel my order.
Minecraft performance with both the i7 5500u and i5 6200u should be very similar, and the only place where they would differ would be AutoCAD, where the i7 would pull slightly ahead because of the higher clockspeed.
