I'm working on scouting out parts for a decent gaming rig, not lookin for ps4 or Xbox one performance, maybe close to 360 . I was considering getting an older PC , throwing a 3-4 ghz CPU ( and some decent gpu( 200$ eBay to start off with then upgrade later). I was reading hat certain computers have a wattage for the CPU and gpu slots, is that wattage for the protection of the motherboard , or is it so you don't fry your power supply? Because I'd be willing to get a 700w power supply, if that'd ensure I don't just completely melt down all the stuff I put Into the PC. I have been reading here and there on how to build your own PC, and I have a decent grasp on it I'm just posing a few questions. I was also going to max out whatever the ram capabilities are.im not extremely picky on graphics, it all looks similar to me, I just want a smooth decent looking gameplay that works with most games, not looking to get hdmi 3d ultra or whatever people obsess about. Just want overall compatibility with most steam games, and I don't want to feel like I'm playing the psx while I'm doing so. Before any negative comments are made, yes I am a noob to computer gaming, all I've ever played on was a Toshiba laptop with integrates graphics, and it couldn't even play most games on the lowest setting. I am trying to get into the steam community, and I am looking for guidance on a few of my questions.
