I wanted to import a r9 270x or a GTX 760......
The trouble I am having is that will it fit into my PC....
My question is that is it the case that matters while installing a new graphics card or the PCI-E version???
No trouble with the PCI-E because I have 2 PCs , one with PCI-E 2.0 and other with PCI-E 3..0,
should my case be the limiting factor?
