I've got vanilla replacers plus a few HD things, I only hit like 1.2GB last time I saw. But I did get a 4GB on purpose - I'll be running with this card for a while... well into the 4k resolution era tongue.gif I won't use 4k resolution until well after it's been out for a while (like what I've done with 1080p) but I will have the VRAM for 1440/1600p when it becomes more affordable for me. I'll be relying on getting a second 4GB 680 in a few years to keep up with graphics, but by then, we should be at 980 or whatever the naming scheme is, so used should be at most $250
Thanks for the quick reply +rep!btw 4k monitors are already out?if so whats the price?

I've looked around, it looks like you can, it just requires a tweak in the registry.
Not sure how reliable it is, I only spent 2 minutes looking so far. Source

Can I mix and match graphics cards with different sizes of memory?

When purchasing a second graphics card, you should try to match the memory size so that you are ensured full value and performance from your purchase. However, while it is not recommended, NVIDIA does offer the flexibility to run graphics cards with different sized memory by using CoolBits. Using CoolBits (value set to 18), you can force both of the cards to use the lower of the two memory sizes and operate them together in SLI mode. When dissimilar memory sizes are enabled to work together using CoolBits, the effective memory size for each card becomes the smaller of the memory sizes.
