New CPU
not to sure on this one but i know gw2 is heavily cpu dependent. so anything with a very high frequency will do well. gw2 for example does very well when the cpu is OCed or turboed. i recently went from a i72600 stock to a 16600k stock (with turbo 2.9) and i noticed quite ab bit of difference. so if it was me i would go i5 6600/k others may think different though.
as for motherboard no idea wont need an amazing one if your not overclocking though.
Either the 4690 or 6600 are fine. 6600 with it’s DDR4 support is more “future proof” as well as socket 1151 motherboards would likely have more recent revs of various standards like USB 3 and M.2.
