CPU :- the 4770 is great, the only problem it has is if you have the stock intel cooler (like i did) with this processor the temps will go blazin' up to 90c, i had to turn off the intel turbo boost to get the temps down to 75c max
CPU Cooler:- a really great cooler slightly better than the 212 evo, 65c max on heave load
Motherboard :- i know i know since i have a locked CPU i should have got the H87 but the price difference between H87 and Z97 was like 2 dollars i was like what the hell :D its a great budget motherboard had no problems with it and i heard its really great for overclocking as well
Memory :- i upgraded from 8 GB to 16 GB only so i wont have to worry about ram for the next few years :p
Case :- i can say only 3 words about this case.... BEST CASE EVER!
Monitor :- i was extremely nervous about this one alot of people said that 1080p on 27 inch is ugly and blurry..etc it appeared that these people are ignorants who judge things without trying them out, i upgraded from hp 22xi to the 27xi and trust me IT IS AMAZING! 1080p on 27 inch is absolutely great! extremely happy with it
GPU :- i had to choose between the 970 and the 980ti after watching alot of benchmarks i realized that 980ti is double the price of the 970 but not double the performance :/ and overkill for 1080p, so i bought this and so happy with it it performs amazing i get 100+ fps max settings on any (decent optimized) game i throw at it on 1080p
PSU:- so i messed up with this one by the time i bought this power supply i had no knowledge that its not a very decent power supply and i couldnt return it :/ i was scared at first but it runs my system flawlessly so far (almost 5 months) and had no problems with it :D
