no actually the feeling of having an i7 is what you get + other stuff that falls in the category of wants.
example of big wants on the gaming system I use on my rig, it's only purely gaming but uses 3960x with 32gb ram, just bought them because of wants but not needs, but imo the fx series isn't as bad as what other people make it out to be, well at least whatever I do I can't make a processor on the same level as amd nor intel, lol I can't even make a processor at all ^_^.
most of the time I host lan party at my place so my other system will get used and not just grow mushrooms on my work room, so far those people I invite are normally happy with low settings on 720p or lower, and for those guys not knowing much about pc besides gaming online using warcraft3 and cabal, and some counter strike, so far whether it was my i3 2100, phenom x2 960t 965be 1090t, fx 4100, fx 6100, fx8120 fx 8150, e6600, i5 2400, i5 2500k, i7 2600k,
so far all of them doesn't notice that much difference (besides the graphics details depending on the platform)
benchmarking there are big number difference but for new peoples eyes besides the nice eye candy of higher end system, all looks the same,
so OT
if your on a budget the best bang for buck is i5 2500k or maybe it's counter part i5 ivy. (don't have any ivy yet)
but if your really willing to pay premium for the extra ego and stuff you would hardly even use or even know they have that feature, then go with i7 2600k or higher, can even go fx-8150 so long as you pair it with a sexy gpu there would be minimal difference that people would notice.
