I don't know where you live but if your budget is $150 usd for a gpu I feel like you can do a bit better than a 750 ti. I just purchased that card for $89.99 after rebate for a budget build I was completing yesterday.
Not that it's a bad card, just think you could get a 950/960 near that price point. Or a I know amd has a few cards that are middle ground between the two, don't have the time to research them right now.
