You people just use that "2x more perf quote" in fanboyish manners. Please stop, it's stupid you aren't devs or anything close to that.
Endlessly I see odd comparisons flourish here. Like comparing multiplatform games and all to prove anything.
Comparing multiplatform games between PC and consoles will always being about bruteforcing things. Why? Basically because those multiplatform games aren't designed to take advantages to platform specific hardware features (and it's the same for console wars bullshit using multiplatform software), so yes more flops = more performance here, always.
PC will always have a power advantage versus consoles, they are just limited by the tech available at a time and that's it. It's undebatable. Problems arise when you compare things that aren't very comparable, furthermore using bad examples (multiplatform games).
Yes, Crysis 3 on PS3 is exactly what you should expect of equivalent hardware on PC (if it does exist) because that kind of game is distributed among a big range of hardwares and isn't designed around the advantages (and flaws) of one hardware in particular. But a game like TLOU is something you can just dream to achieve with equivalent hardware in a PC. It doesn't say PC hardware isn't as capable, I bet if one PC developer would design a game just for that particular hardware (let's say an equivalent tflops and bandwidth config on PC than PS3) he could build a game as ambitious as TLOU because the hardware is effectively as capable.
This particular problem resides in the design philosophy. Designing a game around the hardware of a closed platform improves efficiency by a lot. You can say, to end this, that multiplatform console gaming and PC gaming have the same limiting factors. PC is just like there was plenty of other consoles around there where some have more power and some less, with games designed to run on every of them.
Ultimately, I hear every now and then that consoles are a limiting factor for PC gaming, but in fact the biggest limiting factor for high-end PC gaming is PC. If there was a "label" like "high-end PC gaming only" forming an high-end platform with devs targeting this (and only this) range of high end hardwares only, you would see things right now you never imagine your shiny hardware would be capable of today, things you won't see until the next generation of consoles, right now. I know it's frustrating and it's a shame that hardware isn't fully used and never will be because high end PC gaming is niche (in regards of big publishers) bit it's not the fault of console gaming or even budget PC gaming, it's because devs don't (or aren't economically allowed to) design their games for your hardware.
That's why, in fact, plenty of us choose the console road.
