Ps4 is good but RAM isnt everything. The GPU and CPU is crucial IMO. But still ps4 should be more than capable to push some terrific looking games for the next gen. But also PC gaming will always look good for those die hard PC gamers who will keep up with the latest GPUS and CPUS.
Why bother if its 1.7 or 2.0 Ghz, All I want is more First Party Sony exclusives and to get that in the future most likely you will need to get the ps4. And man graphics are more then good for the next gen, Honestly I dnt wanna play a game which looks too real, then it just wont feel.... gamish to me. Any ways, PS4 is looking strong, and some of the tech demo speaks for themselves. In the end we all know that if Uncharted 3 can look so damn good on ps3, what the heck will ps4 uncharted 4 look...
