I have a Dell XPS that I bought in 2012 that I thought about taking apart to make a better PC rig. I use the computer for gaming, homework, and internet use. I am studying computer hardware/software in school, so I also thought building a computer would help me get knowledge about the hardware. But my friends mainly play on consoles when it comes to multiplayer, however there are some great indie games out there and the single player experience that might be better on PC and/or mod community, even games that my friends won't buy, but I have an interest in. So is it worth building a big rig for what I usually play around with? (no pun intended) What's the best GPU I can buy for my computer now without upgrading or should I go with upgrading? I like 60 FPS / 1080p graphics and I would like to play Skyrim/Minecraft/GTA5(maybe with mods) and the Witcher 3 looks fantastic... any help? I just don't want to spend a lot of money and regret it.
