Recently my EVGA GTX 950 died forcing me to buy a new GPU, My friend upgraded to a 1080 and sold me his bought new never mined on XFX R9 390 for $90, This upgraded the graphical power of my PC immensely but was also a thirsty card, So I bought a Certified Refurbished Corsair CS 650M for $45 that's literally spotless and looked brand new with cables tied and everything. The new GPU improved texture memory greatly and raw power compared to my 950, However my Core i3 4170 was now bottle necking my PC very hard, Which led to the CPU hunt.
So when my friend also decided to upgrade to a Core i7 4770K he sold me his i5 4670K for $70 and it's currently OC'ed to 4.2 GHz running completely fine on a Hyper 212 EVO, Compared to my i3 4170 and GTX 950 my new upgrades put this system at just over 2X faster overall on Cinebench R15, Also went from a 1510 to a 1740 on Novabench 3. Quite an improvement for around $200 spent all in. A little extra for the case stickers but they add a nice touch that I feel completes the look of a PC.
Now I can run more modern games with ease and render videos in half the time I used to be with no issues whatsoever. It's finally nice to have more cores to play with over my old i3, It truly increases enjoy-ability of using a PC. Future plans are to probably add another 8 GB of RAM, Some more blue case fans and a fan controller.
2K-Tan is feeling faster than ever now!
