Im getting a laptop and am on quite a tight budget, i have found one with an I5 processor and 6gb RAM (i can put it up to 8 if nessacary), my only worry is it has an Intel HD 4000 graphics card (its integrated and can use up to 1.65ram i think...), would did suffice for playing Technic on low-medium settings at a good frame rate?
Also ive heard of Optifine? if someone could explain what this is and if it would help with lag (ive heard it would...) Thanks
