It really is not making sense why not so many PCIE 3.0 available.
What language is that?
Anyways, the reason AMD doesn't offer PCIE 3.0 on 990FX/970 is that AMD sucks. Plain and simple. FX is a half-@ssed CPU on a half-@ssed platform. The CPU architechture is stupid, the chipset is stupid, the fact that they are still using a BUS and a northbridge is stupid. AMD will never get their act together. They are too far behind. Once upon a time Intel was lazy in terms of R&D and AMD stormed ahead and was making really great CPUs for a while. Then Intel created Core 2, and AMD has never since caught up.
If you buy AMD your system will only ever be second best. I laugh @ 8 core AMD cpus that only just compete with 4 core Intel CPUs. Weak.
