I found this the other day:

and it makes me wonder if my 590 uses the entire x16 bandwidth. Sucks I can't check :/
My question is: Is PCI-e going to be amazing or will be another gimick?
I mean lets face it, in theory sata 6gb/s sounds amazing but it won't speed up your hdd so thats kind of going to waste. Will pci-e 3 be the same?

Yes, its backwards compatible with all previous generation slots. Slot changes make little to no difference in terms of game performance. Moving from a 1.0 to 2.0 had no effect and that was with the bandwidth doubled. PCIe 3.0 is going to double it again but you still shouldn't see any differences. The only place you might is in tripple/quad SLI/CrossfireX setups. Let me clarify that the PCIe bus was never invented with graphics in mind. It was invented as a replacement for the standard PCI bus. Being faster then PCI and AGP slots there wasn't a reason to not allow video cards to run on it, thus the PCIe x16 lane was born. The improvements in PCIe 3.0 will be so little in terms of frame rate that its not even worth mentioning. The place you will see improvements are in other components that utilize that bus. Such as the PCIe raid controller, it runs in a x4 slot. Before bandwidth was caped to 500 MB/s per lane giving 4x 500 MB/s = 2 GB/s of bandwidth back and forth to the card. PCIe 3.0 will raise it to 1 GB/s per lane giving 4 GB of bandwidth to these cards. This extra headroom will allow people to run more drives without being bottle necked by the bus speed (4x 500 MB/s SSD's will cap a PCIe 2.0 raid controller). It will also future proof in the building of high performance cards that can utilize this speed (PCIe SSD etc).
