As it was explained earlier in the thread, the nature of a GPU's job requires that it has full access to all its resources, hence the memory cannot be shared.

Even in a dual-GPU card like the HD6990(4GB) and GTX590(3GB).

The reality is, each GPU on the card only has access to its normal share.
Meaning each Core on the HD6990 only has access to 2GB out of the 4GB, same goes for the GTX590 with 1.5GB out of 3GB allocated per Core.

EDIT: Also, you're better off getting a custom card (MSI GTX580 Lightning) for buffed up circuitry and PWMs to overclock since it's rather doubtful to use up 1.5GB on a single monitor.

By the time they do use up so much VRAM it'll be time to upgrade anyway.

Google the term future proof, seriously, read a dictionary. Furniture? no sure what your talking about now.
"for me 1 year is not future proof" - opinion, ok? ...
"There is no such thing as future proof in this blog" - huh? some terms don't exist in this forum? refer to defining future proof from google.

well, 2 things here:

1) from what I am reading, the SLI performance increase should be between 60-100% versus a single card. If you're only seeing 30%, something is wrong.

2) 2 580s are significantly more powerful than a 590. Even for single monitor gaming. It also depends on what you play. Some games won't need SLI. But, if you're a Crysis freak like I am, then yeah, you're stuck LOL

SLi 580s are amazing and one of the best set ups out there IF and only if you don't mind the price tag that comes along with it. At 1080p, you can't be beat. Except by like Tri-SLi/CFX or Quad. lol.
