When Oc'ed the 1070ti has the same fps as the 1080. When the 1080 is oc'ed it only get a few more fps. If the 1070ti is bundled with COD i would highly suggest just getting the 1070ti and same that money for maybe a steam gift card
Looks good, maybe you should get the 2600? without X and if i am not wrong the X doesn't come with a cpu cooler so you need to get one.
You may also want to consider a 1070ti instead as it has same fps as 1080
On your profile you say you have a i5-8600k why do you need that disgusting x299... unless you're lying.
(edit) you say you have a 1070 why are you planning a build with a 1070ti? huh i dont get it are you wasting all our time?
so the connectors have two ports, the port that has the arrow is a positive so you need to plug it into the plus the port that doesnt have a arrow is a negative so you plug it to the negative
there should be arrows at the back of the connectors those are the '+' positives and the one with the arrow is a '-' negative.
edit: just reliased your cables already have + and - marks in the front then just follow that
pls mark as answer if it helped THANK YOU I LOVE YOU
