Theyre both pretty much at the same price range. Some things that annoy me tho:
AMD mobo supports sli and crossfire, but intel one supports only crossfire.
Also, intel one doesent have my memory (corsair vengeance 2x4gb) on the support list.
On the other hand - AMD does need more power and runs hotter.
I cant decide - Which one is better for livestreaming and recording while multi/megatasking ?
I also want to overclock them a bit with a stock cooler (Ive read that 2500k can be pushed to 4.0 with stock cooler)
If you're just going to be gaming, average multitasking (game running while web browser, chat, etc), and livestream, then the 2500k should do you just fine. If you're going to be running 4-5 instances of Virtual Machines then I would suggest you get the AMD combo.
I will be gaming while i have opened: chrome on a 17" second monitor and then skype, teamspeak and probably itunes. Can those 2500k four cores handle all of this without getting choppy/lagspikes or without missing a beat ?
Will i be better of getting a fx8120 cause i will be doing a lot of vegas movie rendering and lots of multi and megatasking (coding java, c++ etc.)
Hows the game performance cause i will be playing: terraria, minecraft, league of legends, dota2,guild wras 2, battlefield 3, heroes of newerth and all kinds of games (shortly: i willbe doing lots of lets play content and streams of various games)
I'm no programmer by any means, so I can only comment on games from personal experience (very close friend of mine has an i5 machine I built her). She runs a 2x 1920x1080 monitors, one for games, one for chats, etc. She doesn't lag at all and maintains an average FPS 50 on games such as BF3 and Skyrim (All running on a GTX 560 Ti, btw). What graphics card are you going get? That would be the deciding factor for your gaming experience to be honest
I have a asus directCU II gtx 560 factory OC 925mhz and a corsair gs600 psu.
I still cant decide if i should go with fx8150 or 2500k for the livestreaming and recording ( i do have good bandwidth and a seperate hdd)
