That CPU is fine. The Jaguar performs much worse per cycle per core.
That's basically the same GPU as the PS4, and you'll be able to overclock it since you're not restricted to a tiny case with poor cooling.
Just because the PS4 has 7GB of VRAM available doesn't mean it can/will use it all for graphics. 8GB RAM + 2GB VRAM should be fine (I agree the OP needs to up the DDR3).
If you don't have a keyboard by now, that's depressing.
Who needs a BD-ROM when all of your games are digital.
Yeah.... the CPU in single thread is better but in multithread not because the CPU listed is a dual-core... he needs at least a quad-core in this case.
It's already proved that GPU on consoles reach close to 100% efficience and in PC is more 50-60% efficience... it is the same power but to match a console you will need a way powerful GPU on PC... PC have a lot of overhead... consoles is close to metal.
Killzone (the only game that we knows for sure how much RAM is using) used 3GB VRAM... he needs to increase both VRAM to 4GB RAM and SystemRAM to at least 6GB RAM (the OS and apps on PC uses close to 2GB)... so the PC will have 4GB VRAM and ~4GB System RAM available to games... with the disadvantage of not being shared.
I don't have keyboard... I have a notebook... I think every desktop PC you need to buy something to control the game lol.
PS4 have BD-ROM... you want a PC to match the PS4... so you need a BD-ROM to do the fair comparison.
The CPU has hyperthreading so 4 threads. It will do fine.
Where have these efficiencies been "proven?" I'm going to need to see a source on that. Again, you can overclock a PC GPU, which should lead to gains of 20-30% depending on if you want to modify voltages or not (I'm speaking from my experience overclocking a 7xxx card). The coded to the metal stuff is vastly overstated, especially when the PS4 and X1 share the same architecture with the PC (and share the same GPU architecture).
The fact that you mention 6GB RAM tells me you have no idea what you're talking about. You'd go either 4GB or 8GB to takes advantage of dual channel memory with identical RAM sticks. As I said, he should upgrade to 8GB DDR3 (very cheap). You don't need the exact same memory solution as the PS4. The X1 has 8GB DDR3 and ESRAM. 2GB GDDR5 + 8GB DDR3 should be sufficient.
I'd imagine you are the exception and not the rule when it comes to not having a keyboard or a mouse.
I don't need a BD-ROM when all of my games and media content are either downloaded or streamed.
