So I have thought about this a little bit, I have an RX 480 with 2gb of memory, and i just got it, and got ripped of with a 2gb version cuz I didn't read hard enough because I had never found one with two gigs of vram, so to solve this problem could I crossfire with a less powerful but more vram cheaper card, would that compensate in a game like rainbow six siege, or would it still not work to compensate my lack of vram, I just want to find a semi-cheap solution to my problem
