Bosmer :
I'm just curious as to what the best FM2+ CPU is. I'm beginning to buy parts for my newest rig. Also, is it better for gaming to have hex or quad core processor? My current rig has AMD Phenom II 6-core processor and computes quickly as it should. Are the new FM2+ quad-core CPUs good enough or should I consider a hex core? Finally, would you recommend Intel or AMD?
x4 860k
Its basically the a10-7850k without the GPU.
there's a build that confirmed x4 860k won't bottleneck even r9 280.
Be warned, Intel fanboys would swarm you up in less than weeks saying that AMD sucks in Single Core Performance.
In my experience, I don't really see a disadvantage in AMD besides the high TDP in their cpus.
Ask yourself with this questions :
*Do you care about Wattage? Be reminded that higher wattage declares more power, and more power = more $$ so think twice before you buy. Intel and its 22nm architecture is power efficient <~ the only advantage I think that intel has now? Whilst the new x4 860k is based on 28nm steamroller from AMD, at least 5 TDP least from FX-CPU's and may eat at least a chunk portion of power for that cpu so beware of paying more $$ for your electricity bill.
*Are you budget oriented? Doesn't care about benchmarks but still wants multitasking while you play games? Go for AMD. at the pricepoint. G3258 is the only competitor of x4 860k. If you choose g3258 it would hurt multitasking because of its 2 cores. So be evident about your gaming behaviours. If you play games while recording, running AV programs and Executes more programs at the same time. x4 860k is the real winner. Overclock it to 4.2 ~ 4.5 ghz and you will get negligible performance.
To break this down. Intel = lower power usage amd = better multitasking + gaming [PERSONAL REFERRENCE NO BASHING PLEASE]
Either CPU Brands makes good CPU's.
Extend your research more.
