Dude! Replace the 7870 with a GTX 760! It's $250 as well and performs better than the 7950! Then your build might stand a chance.

dont forget keyboard, mouse and OS.

Point stands as 760 is a great card, but that is a 7870XT...It also beats the 7950 at stock speeds.

We should bump this on launch day and see how much cheaper this PC is by then.

2gb for GPU Ram when even a launch title in the form of Killzone Shadowfall is already using 3.5gb as VRAM is... troubling moving forward, to say the least.

 Buying any card short of 4gb right now seems like suicide for the very near future. Waiting for 6gb on a non ridiculously priced card personally to air on the side of caution considering how RAGE needed 512mb of GPU ram to even start up despite only needing 256mb on console.

This is false. Your GPU ram is only good if it can be utilized by the GPU itself. A GPU found in PS4, with 176 GB/s shared bandwidth with the CPU(more like 140 GB/s for GPU alone) and 1100-something cores can not push enough pixels to utilize 4 GB in a single frame.  Killzone Shadowfas can utilize 3.5 GB of VRAM at some point thanks to texture caching or other elements it decides to store on the GPU, but it will never ever ever ever use 3.5 GB in a single frame, hence a 2 GB GPU would be plenty.

There are GPUs that are 2-3X more powerful than PS4 GPU (GTX 690 and 7990) which cant utilize 2 or 3 GB of RAM before the GPU itself becomes the framerate bottleneck. We're talking massive 5760x1200 resolutions here...

of course no Os and no keyboard and mouse

lol you really didn't knows what are you talking about...

60 AI characters
940 entities, 300 active
8200 physics objects (1500 key-framed, 6700 static)

PS. And the GPU can use all the 176GB/s bandwidth... the CPU will use at max 20GB/s (CPU don't need more).

Bolded: FALSE

I suppose thats the memory utilized by Killzone?

If it is, thanks for proving me right.

This game would run fine on a 1gb nvidia card with its 800mb render targets. some textures may suffer from pop in but it wont be too noticable.

When running out of VRAM, modern GPUs will run into a hybrid mode where the drivers/GPU start streaming texture data from system RAM over the PCIe bus to make up for the "missing" RAM.  All this other stuff can be loaded on the fly as the card needs it...pixel shaders, textures...etc... but if render target absolutely can not be > than VRAM, if it is, you get bottleneck and frame rate drops.

Here is an article for those that think you will run out of VRAM before you run out of gpu juice...

"Battlefield 3 has been NVIDIA’s crown jewel; a widely played multiplayer game with a clear lead for NVIDIA hardware. And with multi-GPU thrown into the picture that doesn’t change, leading to the GTX 690 once again taking a very clear lead here over the 7970CF at all resolutions. With that said, we see something very interesting at 5760, with NVIDIA’s lead shrinking by quite a bit. What was a 21% lead at 2560 is only a 10% at 5760. So far we haven’t seen any strong evidence of NVIDIA being VRAM limited with only 2GB of VRAM and while this isn’t strong evidence that the situation has changed is does warrant consideration. If anything is going to be VRAM limited after all it’s BF3."

So let's recap...
BF3 on high settings, 3x 1080p resolution, 680SLI (3x more powerful than ps4 gpu)...no VRAM bottleneck with 2gb.
