I'm interested in how significant of a limitation the 2GB on the 690 is at very large resolutions. Some information I've seen seems to indicate that 5760x1080 on ultra settings on the newest games ultimately bottlenecks at the 690's memory. While I know 680 4GB in 2x SLI would be a good improvement on the 690, I'm curious as to the tradeoff of clock/mem speed vs. the limited memory. Looking for informed opinions.
