the only ADVANTAGES i can think of choosing between ps4/xbone over a PC are
1. Friend base (most important to me),
2. Exclusives,
3. Ease of use
thats all,
my pc have (indian rupees)
CPU - 2500k, - 11k (aug 2011)
MOBO - Asrock extreme 4 -10k (aug 2011)
Ram - 16gb ripjaw gskill, 10k (aug 2011-16)
GC - asus 4gb double tower - 16k(april, really disappointed they launched rx 580 after 2 days of purchase
)
Total Expense from aug 2011 - jul 2017 - 50k (india)
My pc still performs better than my ps4 in most of the games. The best thing about owning a pc is that i gives you "FREEDOM". Things that you can do with it, the multitasking it presents to you. The freedom to change a part single part whenever you like to(please check the compatibility first.) For the fighting games you can use bluetooth device and ps4 controller with your pc. or wireless xbone controller
The frustrating part on a computer is that some game production companies dont provide better support/port on the pc like gta 4, nier automata and etc etc...
I will not write about speed because it depends on ssd and other components but i must say my pc is WAY faster than my PS4.
NOW, people say pc is expensive for gaming, well lets see,
I will take my own ps4 into account
PS4 - 32k (when i bought it sep 2016)
Extra Controller - 4.5k
PSN - 4k (12 Months)
Total - 40500k
Now you will think its still lesser than my pc, but please keep in mind most of my PC components are from "AUG, 2011" (2 years prior to ps4 launch) and the only significance recent upgrade is my GC
Now the frustrating parts come
NAT issues,
Heaphone Compatibility issues
Contant Updates
Games are expensive than pc
rainbow six siege ps4 - 3.5k,
rainbow six siege pc - 1.2k
At last i would like to suggest, buy a computer if you are a loner like me and dont like to compromise on freedom of usability on daily basis. BUT, if you have FRIENDS who may afford ps4 and if you dont want to get annoyed by missing dll's,and out of date drivers, go for ps4 or xbone.
