Never expected to see the support of PCI-E 3.0 to be portrayed as a bad thing...
It would be less bad if it was all it was cracked up to be. As it stands it was 3% IIRC. Yes, that's well worth ditching my entire X79 set up and buying X99 for (My Titan Blacks do not allow the PCIE 3 hack to work on my CPU).
If I had used hindsight I would still be using my X58 rig. I had an I7 950 and fell for the hype of Sandybridge, buying an I5 2400. Total side grade. My results all came back absolutely identical to the 950. I could have easily made do with the 950 and my UD3 and then stuck a 5650 in and would have been perfectly current. I run four SATA II SSDs in here in RAID 0 and get a gb r/w. So all I would have needed to do was to buy two decent SSDs and put them in RAID which would have gotten around the SATA III missing issue.
I won't be giving up my X79 rig so easily. Give it a couple of years and there will be fast 8 core Xeons on Ebay for cheap.
