Hello, if I have an i7 6700k (a mate no longer needs) and an r9 270x (a total mismatch i know ) can I adapt this build to include both of them?
Always nice to get a spare high-end CPU!
Both it and the video card will work fine with the build as configured, but you won't have overclocking support for the 6700K, and unless your friend gave you a cpu cooler as well, you'll need to add one to the build. For the best low cost overclocking motherboard and aftermarket cooler, see the $1,250 Gaming Build
By the way, TBG recently benched a 270X in an article looking at Battlefield 1 performance
. For comparison, the R9 290 in this article performs identically to the RX 480 4GB recommended for the $750 Budget Gaming Build. That will give you an idea of the improvement in store if you eventually upgrade!
