No I don't, this is my first build, so i'm a little dumb when it comes to component knowledge. I had originally went with a i7(something i don't remember now) and when discussing with a friend he told me the i7 i choose was a little more powerful then i really needed(also a little more expensive then i wished to pay). I didn't really know much differences between the i7s or any cpu other then more cores is usually considered better and ones ending with k are best suited for overclocking(which i dont plan to do until i feel more comfortable with doing so). I do know the i5 is an older model, but it was considerably cheaper and was one i heard mentioned to be quite good, so if you or anyone has a suggestion for a cpu that is better and is $600 or cheaper I'm all ears.
(also thanks for the list of motherboards)
