SAPPHIRE Radeon HD 6670 1GB vs. GeForce GT 630 2GB

A friend of mine recommended the GeForce Gt 630 2 GB for my simple custom build in which I just want to play simple games like Minecraft, Counter Strike Source, and TF2. I found that possibly the Sapphire Radeon HD 6670 1GB would be a little bit better according to a little bit of research. According to game-debate.com, they rate the GeForce at 5/10 while they rate the Radeon at 6/10. Which in your guys' opinion would be better?
