Hardware & Technical Early for a computer spec check?

The video card in the PS4 is a midrange graphic chip. You are confusing memory with performance for graphics and you can't do that. A 1.5 gig graphic card as I use GTX580 will render more FPS, then a lower level graphic card with more memory.

Here is a copy and paste:

Sony states that the PS4’s graphics chip, which is derived from existing Radeon technology and integrated into the Jaguar processor die, can push 1.84 TFLOPS. That number puts the power of the GPU roughly on par with a Radeon HD 7850 video card.

That may seem disappointing because the Radeon HD 7850 is “only” a mid-range GPU. Again, careful consideration allows for more optimism. Reviews of the Radeon HD 7850 graphics card have already shown that it can handle most current PC games at 1080p with medium to high detail, which is a huge leap over current-gen consoles.

So it will be decent but far from high end and to suggest you need a 6 gig SLI setup to match it is wrong. when you go SLI it does not in any way double the amount of ram, it can double the graphic processing but it doesn't use the ram in both cards together.

Read any decent video card reviews where some places up a card from 1 gig to 2 gig to 4 gig of video ram. It may allow for some higher aa setting but not always. At times more ram on a video card doesn't help it at all as far as frame rate or even AA is concerned. Sometimes it may allow one bump up in AA but that is about it. The GPU is more important and no matter how much ram you give a GPU you can't change the amount of processing power it has, the PS4 is still just a midrange chip, and won't get near the performance of a faster GPU card. SLI or Crossfire is not needed to surpass the video performance of a PS4.

That is what I said in my post, 2 cards in SLI doesnt mean double the memory.
2x4GB cards can only provide 4GB worth of graphics quality.
But I thought when it comes to 3D using 2 cards can create the 3d image, providing each eye with the correct aspect at full fps. I may have presumed wrong in that, but that is what is also hinted at in the posters comments I was responding to regarding 3d output.

A PS4 wont be able to do its titles in 3D unless it drops resolution or halves the frames. Which is why I said 6GB x2 sli for 3d at full spec, for standard non 3d then a single 6GB card will suffice. But it needs to be at least 6GB for next gen. As next gen games will use 6GB of GDDR5, i'm not sure what specifically made games for PC exist that have been designed with the sole purpose of using a pool of 6GB+ of GDDR5. By its nature it will be of higher quality than anything another card can do "in that area", no matter the power.
Because PC are generic games are not tailored. Which is why the memory of cards is insignificant compared to the gpu power.
This will not be the case with next gen optimised games.

The power of PC can make a game run at 120fps at 4k resolution but it would still be missing features the PS4 will be doing until it has a 6GB+ video card. Thats the kind of point i'm making.




But its also a mistake to compare Tflops from console to PC. Processing power being the same a console is many times more powerful in results than a PC. An example of this I use is to try and get a PC with 3.2ghz processor with 256mb system ram and a geforce 7600 gpu with 256mb ram to run a driving simulator in 1080p and 60fps like the PS3 does with Gran Turismo 5. It wont happen.
I expect the ps4 1.8 tflops to outperform PC's with 5tflops. Thats with the right studios doing the optimising, and not for multi-platform games. I think its hard to tell what the PS4 games will look like, the demos that we have seen so far from PC developed tools and hardware. An example is that Killzone PS4 demo was only using 2GB of memory, out of the PS4 8GB unified. Its not even the start of optimisation yet.

Does anyone have any comments or experience about mixing AMD and Intel products or the like? I'm looking at the AMD FX 8350 for the CPU but I can't decide between a GTX770 or HD7970. Just wondering if I'm better going for the HD and keeping everything AMD or does it not make any odds?

Won't make any difference at all.

Personally, I'd get Intel CPU & Nvidia GPU, but I don't have any good rational reason for that. The last CPU I bought that wasn't in a laptop was an AMD and a Nvidia GPU. It worked fine until an unknown component went slightly bung and I'm not going to spend anything on it trying to figure out what went wrong (it's too old).

It ran great for me. I have Intel quad core with a Amd Ati 5870 Laptop. You also have to remember AMD rather make sells. So selling the graphics cards to Intel costumers is worth while.
