hi guys , i know that the r9 270 is better than the 750ti i mentioned above but i was wondering of the power consumption difference (75w 750ti and 150w r9 270) ,will the 150w tdp of r9 270 really matters on electric bill? is the r9 270 will blow up our monthly bill? because im choosing between these two cards and im worried on my powerbill if i buy the r9 270. plss help me what to choose.
