Hello Everyone,
I own an ASRock Z68 Extreme 4 Gen 3 running an I7-2600K and two GTX 580's in SLI. I've recently been given the opportunity to upgrade my processor to an I7-3770K for very little. This comes with a number of benefits, first an improvment in IPC but more importantly the ability to run PCIe at 3.0 instead of 2.0.
I realize this will not affect my current video cards, but I intend to upgrade to two GTX 780's in the near future and do not want to bottleneck the cards, especially at high resolutions.
Anyway, I've read the switch ASRock uses on this board, the NXP L04083B, only allows you to run one card at PCIe 3.0. If you're running two in SLI, then the first card runs at 3.0 speeds and the second is at 2.0 speeds. This is an obvious concern when considering micro stuttering and how it would affect the overall ability for two high end cards to render a frame.
Ultimately, I'm hoping someone on here is able to either confirm this happens, in which case I'll spring for Haswell, or refute it. I'm hoping it's not true, as a simple processor swap is much easier than replacing a motherboard, there's a lot of work involved with that, not to mention the added cost.
Thanks for the help.
