PCIe 3.0 and build planning help

[joelarm1998]

I am confused about PCIe 3.0 because it seems like all the modern graphics cards have PCI Express 3.0 x16 connectors, but most of the motherboards I see do not. Am I being blind or am I missing something? Also will putting a PCI Express 3.0 card in a 2.0 slot greatly impact the performance? I am building a system and this is what I have so far - http://pcpartpicker.com/p/pdrmmG I need suggestions for a motherboard and GPU that keep the total system cost between $600 and $650.

Putting a PCIE3 gfx card in a PCIE2 slot will have a minimal impact on performance, but not enough to notice or to cause concern on your part.

A GPU this days can't still cap the PCIe 2.0 lane. It doesn't matter if the board has 2.0 or 3.0

 

A build like this should last long enough. You can add a CPU cooler later and OC, for now the included one should be enough.

I really don't need a HDD for storage because the person I am getting this for does not have alot of music, photos, and stuff. So I think I will keep the SSD I had before
