I am planning on buying a new rig, and I ran into a problem. I planned on buying the ASUS P8Z77-V LX, and putting a MSI Radeon HD 7770 onto it, but when I read the specifications of the motherboard, I ran into this.
It says it has 1 x PCIe 3.0/2.0 x16 (blue), but there is a *2 next to it, so I scrolled down and found this:
"*2: PCIe 3.0 speed is supported by Intel® 3rd generation Core™ processors."
Does this mean I wont be able to use the 7770 without an Ivy Bridge CPU, or am I just dumb? Because it says that the video card fits on the PCIe 3.0 x16, so I'm confused right now.
you can run pci-e 3.0 with SANDY BRIDGE very accurate, there will not any hesitate in performance and will give you its native performance.. Whether you have i3,or i5 cpu's of sandy bridge pci-e 3.0 backward compatible with sandy bridge..
