Its been foreever since I've built a pc(early 2000's) and need a bit of expertiese. Looked at a few sites and I think i know witch way to go but wanted a bit of input. My current(older) computer is a fx-6350 cpu based with am3 socket along wither 4x4gb ripjaw ram(970a-ud3p mobo), and it playes pretty well with most games but i cam across a i7-7700k intel with a ga-z270x-ultra gaming mobo in the garbage and was mainly wondering how much better performance id get over my current setup? Also could i slap my ddr3 ram into this apparently ddr4 ram mobo and would it work? I though i was getting the hang of the amd lingo but apparently not, idk wtf any of this ryzen etc. names are. please help an old fart,lol Oh, also, my gpu is a poopy 750gtx 2gb if that matters.... i have a gtx 660 too.. idk witch i should go with that also. just want something to decently play most games(even though i play mostly backups of my old console games)
