I don't get why and how this could be a bad decision, as i said UNLESS the OP is a BIG planetside 2 or elder scroll player or enjoys playing older games, there is no reason to go with intel...to have the same performance the OP is looking AT LEAST at an intel i5-4670k and this would perform a little better today yes, but not in the future...to get something as future proof as the FX 8 core he is looking at a 300$+ core i7 for the CPU alone...let alone the premium to pay to get an high-end intel board...crazy!
Even in todays modern games (BF4, crysis 3 for example) the FX 8 core performs at the same level and even better than the i5-4670k and you know it i pasted the trusted benchmarks 10 times already...you saw them and you know it...and it will only continue to do so and even better in the future with the way the games are going and with DirectX12 and all the optimisations that has been done to support multi-core CPU's better...windows 8 alone improved performance by about 15 to 20% on these chips, i know it i ran many benchmarks with windows 7 and now the same bench at same speed gigves me much better results in windows 8 (cinebench for example)...all the reviews that are available of the FX on the net are full of flaws and most of them date from the day those chips came out...but we've been a long way since, applications and operating system improvements have much improved on the performance of these chips and yet no newer unbiased reviews have been done since...
Now we are at the point where logainofhades usualy comes in and post his xeon build, wich is nice for the price but we don't know if future games will support hyperthreading or if this is gonna someday really helps in games...
And you will have VnM coming in to argue some vague theory on intel's architecture vs AMD to try to discreditate me...it's always the same.
