Hi, Once Again. Ur Pc specs aren't too bad. U can run almost all games at medium settings if u upgrade to 8 gb of ram. Which games are you planning to run by the way. Tell me and ill let you know at what.settings you can play them in.
I would suggest you to build it yourself as you can do all the cable management you want and u will also save some money. One more suggestion I have is going for a GTX 1080 or a 1070 is much better than 980 and better than a Titan X. It will also be better future proofing for your build. All the best and give me a thumbs up if I gave you good advice or helped you.
Thank You for your support. I will try and get a few more opinions and then start working on it. There is already a windows 10 mobile and windows 10 app for the forums. I will try and bring that to android.
