Hey guys, just curious as to what my options are for GPU’s to suit my build. Looking to upgrade so it can keep up with new games coming out for the next few years. I will eventually get a new rig, but I don’t think it’s super necessary right now. My main question is if i should aim for 1080p or 1440p gaming with this rig in addition to a new GPU. I spoke to a mate at work and he thinks a RTX 2070 would do the job for 1440p gaming but I’m just not sure, as my brother thinks it will bottle neck my CPU. Hope to hear from someone soon, thanks
