Again guys, this isnt going to be an Intel build, its an AMD build. I understand that performance wise, i can get better results with an Intel processor, but at the same time, my wallet likes the price of AMD. As for the usage, its a little bit of everything though mostly gaming. Yes, i realize that most games arent optimised to used more then 2 cores, but i like numbers. That was sarcasm people, dont hurt me. Im just looking to put together a rig that performs well and is some-what future-proof. So the question was, between AMD's lineup of octo-cores and those with experience with them, would i be better served going with the top of the line, could i get similar performance by overclocking one of the lower lines, or does the general public think that the extra cores arent worth the cost over one of AMD's quad- or hexa-cores, which for the intent of argument is the perfectly arbitrary $50-75.
I understand that you like the prices - i mean, ~$190 for "8" cores right?
Problem is, while those 8 cores will actually be 8 real cores for many threaded applications, in others, it really only works as 4 cores, as 2 cores per module share certain resources. It's better to think of it as 4 pairs of cores, where each pair saves on transistors by sharing certain "die-expensive" areas.
The single threaded performance of core-i5 is simply higher - and with 4 real (and powerful) cores, it's difficult to justify the 8 core AMD as others above are also talking i5.
BUT - why not consider the 6300? you're not really losing much multithreading/multiprocessing performance. The cost is more comparable to core i3, and since core i3's single threaded performance is weaker because it's got half the cache of the i5, no turbo, and no AES hardware, the single threaded 6300 performance looks stronger in this fight. At this price point, the AMD actually is a nice option. You'll save a fair amount, and the loss of 2 cores will not be felt really.
A friend of mine is using an 8150 for a minecraft server. Main problem he faced was it's primarily a singular thread heavy process. It however does let him run multiple server instances easily. He hasn't tried overclocking, but as a server, stability is more important.
Lower end lines, especially with piledriver, appear to overclock easily. Common statement is your-milage-may-vary, but i'd say 4.0GHz is a given.
