Hi lads i got some questions about a new cpu that i'm going to buy next month.(If its not the right place i'm so sorry).
1:I stuck between choosing I5 6600 and I5 7600K those two got pros and cons for me here some of them:
If i buy I5 7600k i will get more power (If i'm not mistaken its about %15) but i would need to buy new ddr4 ram with more expensive motherboard and I5 7600K is 110 usd more expensive than I5 6600.
If i buy I5 6600 i can use my ddr3 ram with it and i can buy other things like a new ssd and hdd.
The 7th generation (Kaby Lake) is a very small upgrade over the 6th (Skylake). The main difference is in the clock speed. Both support DDR4 or DDR3L memory. DDR3L is low voltage DDR3 (1.35v). Standard DDR3 (1.5v) is not recommended on either processor. Most motherboards now are designed for DDR4, but there are still a few DDR3 Socket 1151 boards on the market.

If there's that big of a price difference, the 6600 may make more sense.
2: I got a old gpu HD 6970 will 6600 or 7600k bottleneck it?
3: If they can does bottleneck physically cause damage to the parts?
4: Also i need a motherboard suggestion for those cpu's
End note: I'm sorry about my broken English i tried my best also:
1: I have to select from those 2 cpu's
2: Buying from a website is not possible for me
3: How long will they last
2: No. Nearly all games will tend to be GPU limited at resolutions people use these days (1080p +) rather than CPU limited.
3: No - "Bottlenecking" is an overused term which simply means one component (e.g. the CPU) is holding back another (e.g. the GPU). There is no physical "danger" from this. It can cause things like frame skipping. I don't think that will happen in this case.
4: I've now used boards from the major manufacturers (Gigabyte, Asus, MSI and Asrock) and really have no specific brand preference. It comes down to whether you want one with better expansion options, all the newer features (e.g. Ultra M.2, USB 3.1/USB C), or a cheap board that provides minimal features, and of course form factor (ATX, mATX, ITX etc.).
Choose a H110 based mATX motherboard for a cheap basic board.
Choose a B250 based mATX or ATX motherboard for a more fully featured board for a small price increase (supports M.2., 4 x RAM slots, some Crossfire support etc.)
Choose a Z270 based mATX or ATX motherboard for the most fully featured boards and when using a "K" CPU (supports overclocking, SLI on many boards etc.)
1: OK. So no point suggesting to look at an AMD Ryzen or anything else then...
3: CPU's don't have a definitive life. If you mean how long will they still be useful, I should think they will be fine for at least 5 years. Future CPU development is difficult to predict.
