This is it : https://pcpartpicker.com/list/8V82zM
The parts that i already bought are :
The motherboard
The CPU
The CPU cooler
RAM
SSD
Let me know what do you guys think about my first build and help me by answearing the next important question ( at least they are for me though xD ) :
1. Help me get the best ,, ATX Mid Tower ,, case for my build ( i care about how easily you can manage all the stuffs inside it and it's airflow )
2. Do i really have to take care about airflow by the way ? Is that very important to me ?
3. I feel like i should have got and i had the possibilty to get a better RAM / CPU / MOTHERBOARD , like the 7700k and the z270 motherboard , im not expert , i've never seen a comparison between 6700k and 7700k , what do you guys think ?
4. Do you think i should have got a water cooler ?
5. Help me get the source , i have a huge nightmare choosing the one that fits my build ;( ( how many Wats / performance etc. )
6. I want 2k/over 60 fps on ultra settings from this build , do you think that GPU will handle that ? Or i should pick another one like ( STRIX , AMP XTREME , HYBRID ) , i saw that the EVGA FTW couldnt handle 2k/60fps ultra in watch dogs 2 so i'm a bit worried , maybe i could reach that only with a 7700k which i didnt buy ;((((((
7. Should i apply thermal paste on first use ?
8. Any other better monitors than the one i picked ? ( 1440p)
9. I want to buy the monitor from Amazon.Com (https://www.amazon.com/PG279Q-2560x1440-G-SYNC-Gaming-Monitor/dp/B017EVR2VM/ref=sr_1_1?ie=UTF8&qid=1484676990&sr=8-1&keywords=pg279q)
but i live in Romania ( Europe ) , do you guys think it will work here if i buy an adapter ?
10. Do you think the AMD's new processors will work on z170 motherboard ? What about on z270 ?
11. Should i buy Case fans ?
In case i missed anything please let me know and please help me with some tips or whatever you got , it would mean a lot to me since its my first ever build
I appreciate your patience and thanks in advance xD
