I would take a look at the Dell Inspiron 15 7000 (Link at bottom) Its a tad over budget at £899 but its got a sturdy build and its excellent for gaming with a GTX 1050 Graphics card (Really good card) and an Intel i5 CPU (Pretty good CPU) which should have no problem with big games like GTA5 on high settings. One bad thing about it is that it has an SSD which means less storage but faster loading times.
