With what you have I would say SSD unless nag apas jud kas highest possible framerate sa imong PC. The last upgrade I made is an SSD and I should have done it sooner.
I dont know why ang mga tao e promote sa SSD ang boot up times jud, I mean its fast.. 8seconds compared to 1min on some systems but the biggest benefit SSD gives is AFTER booting, your system is over all more responsive.
though I understand people who are not convinced by SSD will say so other wise, ana pud ko sauna.. boot up speed raman.. I dont even reboot my PC for weeks but pag SSD nako naka igon ko the boot time is the very lease of its benefits.
