Some games like Medal of Honor reserve a percentage of your Vram whether it uses it or not, so it may look like it is using a lot but it is not really effecting gameplay.
I don’t get this. The vram does not stack, or am I bonkers? So with 4GB x3 you would have 4GB ram available total in the system still, while having, let’s say 2GB + 2GB + 4GB would land you at 2 GB as the third card would only use 2GB ram to sync with the other two cards? As things stand with memory consumption now, which barely gets to 4GB, you would only benefit from >4GB Vram in applications outside of gaming.
