The 360 only had like 512MB of ram and still pulled off some damn impressive things. The fact that these consoles on a hardware level are behind PC's doesn't matter because the way the hardware is being used is way different. They can squeeze way more out of way less. I don't think we've hit the ceiling just yet with these things. I think the true showing of what the Ps4 can REALLY do is going to be when you see Uncharted 4 drop.
