Sacrificing quality just to fit budget for a hard drive but picked the 470 over the 1050ti? So your saying the 470 is better then the 1050ti which is fine and dandy but why buy a shitty hard drive? Also if he does lightroom and photoshop why limit himself to such a small data drive? So no, you aren't thinking outside the box.
Small sata drive? He has a 250Gb SSD my friend. 250+320= 570. Which is more than the one that the 500Gb SSD had. I chose a shitty HDD because it´s on budget. Why the hell not? He already has an SSD, why doese the secondary mass storage Drive has to be fast??
