Look at past generation CPUs... (Core 2 Quad, Phenom II, etc) they are chips that will last an insane amount of time for gaming, so imagine what the 2500k will do

But hey, it's your money man
I bought the 2500K over the 2600K because I only game. It really depends on the price but I would really like a board with two 16x lanes for my upcoming Eyefinity setup.

I think you need to read THIS.

LGA 1155 won't be the dead end that LGA 1156 was.

Upgrade path FTW!

Where are you getting this from? The 2600K only provides a noticeable difference at 1024x768 and below. A person shelling out money for SB is not going to be playing games at that low of a resolution. And Far Cry 2 shows a difference of a few FPS at higher resolutions. Put that $100 towards a better GPU, that's where the performance will really be noticeable.

As far as optimization, game developers have a poor track record with this especially since now they are designing games with consoles in mind. I'll believe it when I see, for now it's just marketing jumbo.

I like how you say the PIIs are 2 years behind and then mention video encoding where they match most of the last gen i7s. You might as well say the $200 2500K blows away everything except the $1000 980X in video encoding (of course excluding the 2600K).

USB3.0 is already available on a majority of boards for all platforms.

Again, read.

All the current SB users will need is a BIOS update, and voilá. Ivy Bridge awesomeness on P67 and H67.

Hyper-threading helps in some scenarios, in others it can cause performance to degrade (Test LinX with HT on and HT off and compare gflops, for example) and in most it doesn't provide much of a performance increase at all.

Video encoding? The Thuban beats Nehalem at least, iirc, not sure about SB, although it has always been one of Intels strong points. (Mainly due to the Intel compiler not using SSE2, SSE3, SSE4a, etc if it detects an AMD CPU up until Core 2 Duo, as AMD was faster or equal then)

PCIe 3.0 is completely up to the CPU to be honest (The NB is on die with 1156/1155 CPUs), plus most users won't need it anyway, USB3? Most users have it already with the NEC chip and Lightpeak? Not many people will use it until there are enough devices that use it, or some kind of USB3 > LightPeak adapter.

I don't expect clock for clock performance to be more than a 5-10% improvement.
This, there won't be much, if any, improvement to most i7 2600K or 2500K owners if they're at around 5Ghz.

It's still more about the platform to me though, 1155 simply isn't the enthusiast equivalent that 1366 was at the time. I think it's great IB will be available to 1155 boards as well, but I'm still shooting for 2011 after a little bit more saving up.

1366 suffices and will keep doing so for a good amount of time, why renew when you already own near the best stuff available.

20-30% increase in performance is to be expected...a die shrink means you can stuff more cores onto the die at higher clock speeds.

I just got SB and I love it, hopefully this will be a good upgrade (pointless but fun)!

I thought it just meant it had lower heatout put, so can be clocked higher. I don't think more cores are added

They are, the 980X has 6 cores and is a dieshrink of Nehalem (4 cores max), and the heat output of SB is pretty small to be honest, I think once we get a new CPU stepping, 5Ghz on air will be very common.
