I'm wanting to add another gpu to my build (4770k cpu). I know the i7 4770k can only support 2x16 lanes of PCIe support, adequate for a standalone SLI setup. However, I've got a new Intel 750 series SSD also on the board. Am I thinking this correctly: the lack of support for that many lanes will either bottleneck performance of the SLI gpu's and/or inhibit use of the SSD? So the only way around this is to upgrade my cpu and thus my mb? Thanks in advance.
