its been a while since my last build and I'm eyeing the 29" 2560x1080 monitors. I see the new i5's will power 4k resolution with out discrete cards. Would I be able to even run the super wide screen 21:9 monitor without a discrete card? I'll get one later. I'm looking to build around cyber monday when newegg runs their sales. those big @$$ 34" plus the $600 gpu to run are a little too steep for me right now with a full on new build plus monitor costs. I also see that the i5 6400 is about $80 than the unlocked 6600k. would it be better to use that towards a better GPU?
