I was hoping someone might be able to help me out with this comparison. I'm having a hard time tracking down benchmarks for the ATI Mobility Radeon HD 3400 in order to compare it to the Intel HD 4000. I know the Intel is an integrated chip while the ATI is a dedicated mobile graphics card, but its also from 2008. I am very likely going to go with the 13" rMBP and I just want to ensure that I'm not downgrading in that regard. I don't do anything pressing, just casual RTS every once in while when I'm really bored, but I still wouldn't wouldn't want to get any worse than my already five year old graphics card. Any insight is greatly appreciated.
