So it is my first time building a gaming pc and I really want to get the best possible rig for my money! I am currently having some trouble selecting a gpu. I am leaning towards either a r9 290 or r9 380 but don't know which will run the best. I've also looked into a gtx 970 but have had trouble fitting it in my budget of about $800-$850. My goal in this pc is that it will be able to run higher end games like advanced warfare, gta v, and batman: arkham knight, etc. at really good settings. Thoughts or suggestions? Thanks in advance!
