okay so im going to put my word out there. @op the current display you have linked is more for fps and shooters (because of its sub 2ms response time) i would look into ips displays if your more concerned with graphics than extreme speed response times (the difference is not that easily differenciated). also do you posess the knowlage to build youre own computer? if so what dan lightbulb posted is a very good build that i would highly recommend

.@dan, i wouldnt believe the hype. amd is losing steam in the GPU race imo. most of theyre cards are cheaper, but theyre performance reflects that. i do have to admit the R9 series are really good cards
@OP (again) it might be a good idea to switch out the i5-6400 on dans list with a i5-6600k, its the CPU i use and it has not given me any issues
