I recently built my new PC rig
The motherboard is H87M-E which has one PCIE 3.0/2.0 x16 and three PCIE 2.0x1,
and my Graphics card is Inno3D GTX 780 Ichill HerculeZ X3 Ultra which requires 3 PCIE slots
I want to ask if i put the GTX 780 in the H87M-E , the top slot is 3.0x16 and the other two are using 2.0x1 , will i face any performance loss with my card ?

You can't put it in both at the same time. you can only put it in one pci slot at a time, and then the physical size of the card fills up the other two slots. If you plug it into a 2.0 1x slot then you will lose a lot of performance.

Each of those little protector plates on the back of your case counts as 1 pci slot. The graphics card itself only has 1 connector that plugs into the motherboard into the 3.0 pci slot, but due to the size of the card, it will require the space of all three slots

no, just make sure you have the board properly installed, and make sure you screw the card into the case securely (will be on the left hand side of the card where you had to unscrew to remove the plate that was coveing the pci slot before you installed the card (remove all pci covers (the little metal things on the back of the case that will need to be removed for the gpu to fit in). only remove the ones needed
