Went yesterday to buy some more RAM. Already had 8GB (2x 4GB), bought 8 more GB (2x 4GB again). I now have 16GB of DDR4 RAM. I'm ready for QC & streaming :D.

cpu : i5-6500 (4 cores at 3.20GHz up to 3.60GHz with turboboost)
gpu : GTX 970 4GB
hdd/ssd : crucial something 250Go SSD and Seagate something 2To
ram : 16GB DDR4 (4x 4GB)
monitor : benq xl2411z (144hz @ 1920x1080)
mouse : zowie ZA11 (@ 1600dpi 1000hz ~11.3cm/360 no accel)
mousepad : goliathus speed extended (XXL one)
keyboard : ozone strike mech black switches (solid as fuck keyboard, last longer than any steelseries mech keyboard)

250fps @ QL
144fps @ RFLX (feels smoother than QL)
152fps @ OW (feels just as smooth as RFLX)

If my graphic card doesn't allow me to play at 144fps with lowest possible gfx settings @ QC, I'll get a GTX 1070 8GB. If I can already play QC @ 144fps stable with my GTX 970, I'll be fucking happy :D.

COME ON QC I'M WAITIN' FOR YA!!!!!
