Please rate or recommend suggestions to my build, I'll be mainly using it for gaming.
I5-2500k (planning to overclock it up to 4.0-4.3Ghz)
Asrock Z68 Extreme7 Gen3
Sapphire Radeon 7950 3gb 384-bit OC Ed. (planning to overclock it more with the same voltage)
Corsair VEngeance 8gb (2x4gb) Ddr3 1600 or G.skill Ripjaws 8gb (2x4gb) ddr3 1600 9-9-9-24 timings and 1.5v
Switch 810 or Corsair 500r (I still haven't made a decision on what case to buy)
Seagate 500gb HDD
Seagate 128gb SSD
Do I really need Corsair H100 for this build and I would like to cut some costs on unnecessary parts, except the GPU.
Not bad, there are just a couple things you need to change.
First, I would definitely get the newer i5 3570k over the i7 2500k. They are the same price, the 3570k has a slightly higher clockspeed than the 2500k and will beat the 2500k clock-for clock (ie, it would be faster even at the same clock speed) It also uses 77w compared to 95w on the 2500k, making it much more efficient. It also has an unlocked multiplier for overclocking, and the newer HD 4000 IGP from Intel and it supports PCIe 3.0
Second, DO NOT get a Z68 motherboard. Z77 is better in every way, is better for overclocking and has been made for the latest ivy bridge (support for usb 3.0 and PCIe 3.0, etc..). The motherboard you listed isn't even on Newegg anymore, it has been discontnued as it is now obsolete... I have never used AsRock before, so I have nothing bad to say about them from my own experience, but i will say I haven't heard great things about them and I know there arer better manufacturers.. I would strongly recommend getting a motherboard from Asus.. Also, this motherboard supports LucidLogix GPU switching technology, which means you can run on the IGP until you run a graphically intensive program that requires the discrete GPU, which saves more power.

For the GPU, you can't go wrong with the card you selected. Me personally, i would go with an equivalent priced Nvidia GPU, but that is only because I'm an Nvidia fanboy, since most would agree that the 7950 is a better card with better overclocking capabilities..

For the Cpu cooler, yes you could cut some costs by going with a cheaper one, but I wouldn't if you plan on overclocking.. That being said, the h100 is massive, and you would be more likely to run into problems fittingit into a mid tower case, and a push/pull setup would be out of the question... I would definitely go with the h80i, it comes with a double thick radiator with push/pull fans out of the box, will stil fit better because it is not double-wide, and will give you lower temps than the h100, all wthout being significantly louder.. basically, h100i > h80i > h100 > h80.

For the power supply, you again made an awesome choice! you can't go wrong with that power supply. However, right now you can save 20 bucks on the newer TX 750 v2, which has equivalent or better specs, just with 80+ Bronze certification instead.. many would argue that it is worth it to spend the extra bucks for the higher certification, me personally I wouldnt really care, it's not like you would notice a difference in your power bill and it's not like a power supply from corsair is going to die sooner because it only has a bronze certification, they are all good quality..

Again, Great choice on the RAM.. I have never used G-skill, so I would go with the Corsair.. Also, i would advise getting the low profile.. Giant cheap heatsinks on RAM are pretty much just for looks, and are more likely to get in the way of something.. http://www.newegg.com/Product/Product.aspx?Item=N82E168...
For cases, ether one you choose would be great! I would go for the 500r, since i don't really think a full tower is necessary when a mid would fit everything you need just fine, and you could save a bit of money... So of the two, i would definitely go with the 500r, me personally i would go with the Vengeance c70.

CONCLUSION: The above parts are what I would get. Most of them are just my own preference, and the ones you picked would be fine, WITH THE EXCEPTION OF THE CPU/MOTHERBOARD.. Like i said, there is absolutely no reason to pick a 2500k and Z68 motherboard.
@dns7950, I think i can't spare 250$ for the sabertooth z77, would the asus p8z77-v lk be good enough or overclocking??
I would your advice to use i5-3570k insted of the 2500k,
sorry my mistake I actually meant a samsung SSD lol
thanks for your suggestions,
EDIT: I went to asus website, sabertooth z77 is worth every penny so I'd go for it.
I agree, the sabertooth is definitely worth it if you want to overclock and you can afford it. That being said, you could probably still achieve a fairly decent overclock with the p8z77-v lk, but it is just isn't in the same league quality wise. So again, if you can afford it get the sabertooth. if not the p8z77-v lk is a great board for the price. Either way, you're gonna have a pretty sweet gaming rig! I'm jealous.. Good luck with whatever parts you decide to get!
