I dunno about it being a 780i but I know it's a 7 something. I also don't think 32x (PCIe 2.0)slots are going to be all that needed yet. Sure it'll reap better performance for those who want the new Nvidia G9* later on but that's pretty much it. I'm not even sure the 8800Ultra saturates all that the 16x slots have to offer.
I know I'm not going to run out and get another 500+ card just to be bottle necked by PCIe1.0 and I know if I got a PCIe2.0 slot it'd just be a waist of money for long time since 16x is still going to be pretty good. By the time 16x slot aren't fast enough it'll be at least a year and a half from now. Even then they will still be super fast, just not the fastest. It's like going from an 8800GTS to 2x8800ULTRA's in SLI with a QX6800. You can see that one system will be super-duper fast but the performance of the 8800GTS is still pretty darn good and the price difference is huge. Also like having a 1200watt PSU for a 8600GT(i.e, overkill) :roll:
I know one thing I'd like to see, and that's another one of those pci express bandwidth comparisons like THG did before. This time though I'd like them to include the GTS, the GTX, the Ultra, and the 2900XT.
I'm sure PCIe2.0 will be faster but at what cost and is it even needed?
