Is there a relation between PCIe x16 of processor and PCIe 3.0 x16 of motherboard? I have a PCIe 3.0 x16 slot in my graphic card that can go with motherboard but i need to know about the other thing;i.e; processor and motherboard. I have i5 (3.2GHz), Zotac Nvidia GeForce GTX 650 Ti 2GB DDR5 graphic card alongwith 8GB DDR3 RAM. What would be the best suited motherboard for this configuration? Is ASRock Z77 Pro3 a good option? Also tell me if 450 watts of power supply will be sufficient or not? I am not planning to go for SLI/Crossfire in the near future.

I'm guessing it's the i5-3470 since it's 3.2 GHz stock speed, am I correct? Anyway, the Z77 Pro3 is a good option if you want to overclock (yes, you can OC non-K i5 a bit). You could save some money by opting for an H77 or B75 chipset motherboard. A good H77 is the AsRock H77M, $70 at newegg.

450W should be sufficient for GTX 650 Ti IF the PSU is 80+ certified. I'd recommend an 80+ certified 500W-550W power supply for that card if you haven't yet bought the power supply. For SLI, something more like 650W.

The CPU doesn't go into the PCIe x16 slot of the motherboard, it goes into the CPU socket. The graphics card goes into the PCIe x16 slot.

the processor provides 16PCIe lanes to your motherboard so there is a PCIe contrller on the prcoessor.the best suited motherboard is chosen by you you need to first know what you need or want.you dont need z77 unless you are overclocking your CPU. (PCIE slots,Sata ports, IO ports ,internal USB connections ,Fan headers ,UEFI bios and other such things. For your power supply i think 450w will be enough but search into google extreme power supply calculator and then click the first link fill in all hte parts in your build and then it will give you a wattage.

Yes, I'll be OC my processor as well as my graphic card. So, in that case what motherboard should I go for?
