The issue I usually see is not so much that the card is not powerful enough, but that the game uses some kind of feature that JUST came out, and only new cards have it. You can have all the GB of ram you want on the card but if you don't have that one feature you're screwed. Stuff like pixel shader 1, 2, 3 or whatever they're at now. They seem to just be pumping these things out way too fast.
You should've read all the bitching and crying and whining from the cheap asses on the Eve forum when CCP announced they were dropping support for pixel shader 1 and 2. You'd think they were going around shooting people's dogs and raping their mothers instead of simply trying to keep up with graphics technology.
