So my current rig isn't brilliant by todays standards and I'm thinking of getting a GTX 1050 maybe a Ti to replace my GTX 650, my worry is about bottlenecking the card, be it motherboard or CPU, cooling and power are fine. My current CPU is an old quad core i5-750 (from the LGA1156 socket days) and my mother board is a Gigabyte GA-P55-UD3R. I'm not worried about my power supply as its a 700W OCZ PSU (Overkill I know). So as far as I've researched the CPU won't bottle neck the card at all if only a rad in more CPU heavy games upto a 1060. My main concern is my motherboard being PCIe 2.0 (Can't recall if its x8 or x16). SO... Will it run or am I better off rebuilding this old rig from scratch? Also I can upgrade to an i7-860 if needed and I'm curious if that will be able to handle a GTX 1060 or even a 1070.
The games I wanna play: Dark Souls 1,2,3, Dragon Ball Xenoverse 2, GTA V, some Xbox 360 titles such as Splinter Cell Conviction. etc etc. I also am currently doing PS2 Emulation (I am aware that this is more CPU intense than GPU)
