Hey guys i have an Intel i5 3470 @ 3.2ghz and a pretty standard motherboard with 8gb ddr3 ram and soon upgrading to 750w psu. I currently have a gtx 750ti in my build and looking to upgrade to a gtx 970, will my cpu bottleneck this graphics card or will i need a new cpu? (ideally just buy the graphics card as i don't want to spend a lot of money)
