Hey guys! Thanks for this thread!
Did the 4 GB type come out later and they beefed it up?
There is no diffrence between the Cards except the ram
do not get the 4GB version, it's just not worth it. The 770 can make full use of the 4GB of vram, if you need more vram because you're playing on multiple monitors go AMD or 780, 770 won't do it.
