Conspiracy theory at best, combined with your favourite falacy - a circular argument. Goes like this: "BF4 engine = BF4 engine because you cant show me the difference therefore BF4 = BF4"
Please, go to school and learn about fallacies.
5-10FPS LOOOOOOOOLLLLLLLLL.. seriously? You think a 680 is only 5 - 10fps slower than a 780Ti?
Not may, ARE wrong. The 780Ti smashes the 680 in every thing...
and about the same as a 690 (which is 2 x 680s)
Fail, System ram and VRAM work completely different. Please show any single reference to your claim else it doesn't exist. 50Mb VRAM over 3GB VRAM is within the realms of error, not some 'reserved portion'. Please show any reference for your nonsense.
Because I cant PROVE that BF4 is running the same engine as BF3 means that it isnt? Well that makes even more sense. If it looks like BF3, it is BF3. And thats the case. Its not a circular argument at all, its plain and simple they did nothing to increase the graphical quality or the performance so how can they claim it to be running a brand new engine?
Its not just system RAM. I said ANY storage device. Your hard drive, solid state drive, your ipod, your phone. Anything that is a storage device cannot use 100% of the physical memory available. Its always been that way since day 1. Why? I couldnt exactly tell you. Perhaps its a marketing gimmick.
Show me your card using 100% of its VRAM then you will prove me wrong. Otherwise, you have proved to yourself that its not using 100% of the total physical VRAM.
5-10fps I was obviously comparing the standard 780, since I clearly stated that I was comparing it to the standard 780.
EDIT: First off, lets drop the whole your computer versus mine. Its obvious yours is faster. Its also obvious that mine is no slouch. Hardly a "medium" build. If I can max out every current game at 1080p with 8xAA and still get more than 40FPS average, that to me is a high end system. May not be the fastest, but its high end. Was top end when I built it.
Secondly, in response to the VRAM usage I will go back to the day where I had my 320MB 8800GTS. Here is a PERFECT example of how VRAM works and how it is important. With this card, I could NEVER use more than 312MB of VRAM, and I specifically remember posting in the screenshot thread asking why it would not use the full 320MB and if I really cared enough to prove it to you Id go dig it up from like 2 years ago. However, until you can prove that you can use all 3GB of your VRAM then by all means. So far, you have posted it as using 2.95GB which only proves my point I feel that I dont need to site any sources that say exactly what you are seeing yourself. Also, because I dont know exactly where to find such specific information.
Thirdly, staying with my 320MB 8800 I was shown exactly the importance of VRAM and what happens if you dont have enough of it:

I mean, we are talking about an average of a 26% increase in overall performance. Just from having double the memory. Same exact GPU. It shows how having the right amount of VRAM can drastically effect your GPUs performance. Which goes back to my original statement that if the OPs graphics card has 1GB or less, if he plans on running games on high he will be exceeding that 1GB mark and his video card will be constantly reloading its memory and while that happens the GPU is doing nothing but waiting on the memory to reload.
And thats how VRAM effects gaming performance.
So just because you have all this money to throw around on the best equipment does not mean you know everything about the equipment you have.
If you look closer at the sited benchmarks from that link I posted, you will see that even SLi 8800 320s could not outperform a single 640 8800. Because even with double the processing power each GPU was still sitting around waiting for the VRAM to constantly reload.
