My question is why you are considering the HD 4000 after all the posts about that and games?
1.Dell with an i5 processor and AMD Radeon 7730m, with 6 GB RAM or HP with i7 and intel HD 4000, with 8 GB RAM?
2.How good is Intel HD 4000, NVIDIA Geforce GT 630m, and AMD Radeon 7730m compared to each other?
