So, anyone know if Radeon R4 graphics driver is better than Radeon 6520G? They're both entry level and integrated but the latter is what I had and R4 is what's in the new thing, it seems to be better/as capable as the 6520 from what I've seen, but I'd like to know for sure (everything else in the new comp is better than my comp that just died, this is my only concern xD)
