You are making the right choice. LA Noire killed my beast 60gb a couple of years ago, and I decided to buy a slim earlier this year. It's so quiet I don't even know its on.
Bullshots, really? Look at the Police marking on the left side of the car, all blurred. That's likely taken straight from in-engine. I see some jaggies in far out objects which wouldn't be there if they heavily downsampled these either.
How is that on subject? It was never announced, hinted, or mentioned that it would come to those platforms. We know it will (eventually) but that is about as far OFF subject you could get.
