witch better AM2+ or AM3+?
This is a little vague because there is noAM3+ as previously mentioned. But more so because it can apply to processors or motherboard.
1. In terms of processors, AM3 is better because it is newer architecture and much faster than AM2+ processors.
2. In terms of motherboard, the AM3 is better because it supports DDR3 RAMs.
Please do not confuse motherboards labeled as AM2/AM2+/AM3 or AM2+/AM3 as AM3 boards. They are still AM2+ that supports DDR2 RAM but they can support AM3 processors.
