Hi im building a gaming rig and i would like to ask whether the 50-60$ difference between the r9 270 and gtx 760 notable in performance. Ive seen "r9 270x vs r9 270" here and it says that the difference between the r9 270x and r9 270 is not that much so its a waste spending 40 more dollars for the r9 270x. I was wondering if this is also true with r9 270 and gtx 760. I dont have much money so im saving where ever i can. please help
