Intel's new onboard GFX are very powerful, better than AMD's now. And pulling ram for IGP is not a big deal if you have atleast 4gb and will not ''slow things down''.
The DV4 looks to have an AMD turion II cpu, correct? Not an intel I5. The I5 is a WAY better cpu, and the intel graphics are way plenty good seeing how the resolution is only 1366x768 on that laptop.
