for a gaming rig, get the i5 "K" variant and a monster GPU then OC'ed both... an i5 is bang for the money compared to an i7 on a gaming rig...
personally, wala pa gani ko maka kita'g reason to upgrade on my heavily OC'ed i5-2550K and GTX 670 2-way SLI... karon, nag palit naman ko'g Witcher 3 (padung pa'g DL... on queue pa sya sa mga games na akoang napalit sa Steam)... sure ko, mo kamang ang GPUs nko once maxed out ang GFX setting aning Witcher 3 pero, pwede ra man ni i-adjust ba... i-off ang hair works. mao man ni ang taxing kaayo's GPU dba?. if naka off ni, nice ra man gihapon ang GFX sa game... hehehehe...
anyhow, kun dili mag video editing na mo gamit sa power sa i7, better suited gyud nato ang i5 (K variant para ma puga pa gyud ang performance through OC'ing) w/ a monster GPU... either single or dual configurations...
then on AMD's side, the FX-83xx series... if you'll want go the AMD's route... price wise & availability, no idea ko dha's Pinas ani...
