I need to replace the HDD in my laptop. It recently malfunctioned and needs to be replaced. I need to know, if these components will work in the specified systems and in your opinion, which of these two should I repair. I'm a student right now and I don't have the cash to completely build a new one and I really only play Valve games, World of Warcraft, League of Legends and Minecraft for the moment, I don't have time for the more popular games anymore.
For the GPU, I'd say that is a good choice since you have an older PC. The only other card I could recommend is a 7750, but that's about $100. You will also want to check your power supply. I wouldn't install that card if it's under 300W. Normally I'd say 350W, but you have sporting a Celeron which would consume less power than a higher model chip.
