Microcenter/costco for gaming PC

Hi. I don’t have much experience in the PC world, but I need both a new gaming platform and computer,so I figure a gaming PC makes the most sense. Does anyone know of good deals for prebuilt gaming PCs at either Costco (supposedly they have decent builds?) or micro center? I’ll do some research on my own, but all of the specs are a bit overwhelming to a newcomer, so I figured I’d ask for some pointers in the right direction. Thanks
