ASUS M5A97 vs ASUS M5A97 R2.0

[AMDRadeonHD]

What's the difference? What does R2.0 mean?

R2.0 means it's the second revision, as in they've changed something on it and released it as a new version. I couldn't tell you the difference without looking at the specifications, but if they felt the need to release a second revision, it's safe to say you should go with that one.
