The RAM crunch has been a quiet victory for those older cards. I have a 10 year old video card in my rig that had at the time a decent but not chart topping 8GB of RAM. Developers are still targeting 8GB because so many of the cards released today still have that. Since I'm still using 1080p the performance is usually acceptable too. Surprisingly the biggest problem is becoming the CPU, with the i5-3570k lacking a few of the later SSE instructions and being completely unable to run some titles.
