I have i5 750 and dp55wb board . I am looking to buy haswell..i5 4570 with gigabyte H87-hd3.. is it worth a change or I stick with my old system.. just a little worried about the pci express x16 slot, cause mine is ver 2 and new is ver 3. and some ram issues

Broadwell is not going to be much of an improvement over Haswell from a CPU performance perspective. The main goal is to reduce power consumption and improve the integrated graphics core. Much like how that was the case for Haswell and again for Ivy Bridge. I would guess that CPU performance will improve by another 6%; early estimates puts the graphics core performance increase from 30% - 40%.

The average CPU performance increase from generation to generation is as follows assuming the same number of cores and the same clockspeed.

1st gen -> 2nd gen = 12%
2nd gen -> 3rd = 6%
3rd gen -> 4th gen = 6%
4th gen -> 5th gen (Broadwell) = 6% - this is an educated guess

Based on the above the average performance increase from 1st gen to 5th...

You shouldn't worry about PCIe Gen 2 compared to Gen3. There is no real life performance difference between the two. Even the newest cards can't saturate PCIe Gen 2 so you should be fine in that aspect. Upgrading your CPU to haswell is a pretty big improvement but you shouldn't upgrade if your only reason to is to upgrade your PCIe Generation. If i were you, I would wait until Broadwell comes out and then buy that instead of Haswell.

so will broadwell bring a big boost in performance and features as compared to haswell. cause I was looking to buy a new system cause my graphic card died and been using this system over three years. so you recommend that wait for broadwell instead of buying haswell. so should I just upgrade my graphic card . like gtx660 which I am looking to buy . and save rest of money for braodwell...?

Yes that's what i would do. Grab a Graphics card now because your current system shouldn't bottleneck it and then save up for when broadwell comes out. Haswell has already been out for over 6 months so broadwell is right around the corner and it will be 14nm compared to 22nm that Haswell is.

so it will be more faster than the haswell. ok wait and see.. my power supply has two 12v rails each provides 18 amps.. PSU is FSP bluestorm pro500.. is it okay to install gtx660 on it . or it is insufficient to provide much power to GPU.. ?

I'm not too familiar with that PSU but it should work just fine. How much is the GPU you're buying and could you give me a link to it?

yes the new broadwell CPU's will be socket 1150 but they won't work with the Motherboards that are 1150 right now :/ so those who have haswell and want to upgrade to haswell will have to buy a new MOBO as well as a new CPU

i'm guessing you can't OC your CPU on that board? Haswell have that couple of % advantage per MHz.
Still Your I5 should be ok for modern games and with GPU like 660(ti) it would work well

Your PSU is also ok. It's FSP group.

If you feel your current system provides you with good enough performance you can wait for Broadwell if you wish. However, if the difference in CPU performance between Haswell and Broadwell is just going to be another 6%, then you will not really any difference with the two of them side by side. Unless you run benchmarks.

While an increase of 30% - 40% in graphics core performance may sound nice, it will not be comparable to a current dedicated graphics card. At best it might mean that Broadwell's graphics core might be at best close to a desktop Radeon HD 5670 which is faster than the Radeon HD 6670 DDR3, but slower than a Radeon HD 6670 DDR5.

if still interested about psu it should be enough cause cpu consumes 100w , gtx660 140w , motherboard+optical+hdd(/ssd) i assume max 100w . your tipical max consuption should be no more than 350w , and your 500w psu if has 80+ cert. it must give you 400w minimum , let's make that 420~430 max output . if so you still have at least 420-350 , 70w safe zone .Make sure your case is vented and don't overclock nothing (welll.... ok but maxx 10%).Also make sure you won't put in any card that consumes more than 160w.
