I7 2600k for overclocking

Hello, everyone~ I'm a very newbie in this world with only one time experience of building up my own configuration 10 years ago :ouch:  Basically, I would be using this laptop for programming such as C, Fortran, and Matalb. I don't expect to use it for gaming purpose whatsoever. Fast and efficient computation: that's all.

cpu i7-2600k $307
cooler Cooler Master Hyper 212 Plus 120mm Sleeve $25
vga Evga GeForce GT 430 1024 MB DDR3 PCI Express 2.0 DVI/HDMI/VGA Graphics Card, 01G-P3-1430-LR $55
board ASUS P8P67-M PRO <REV 3.0> $135
power Corsair Enthusiast Series 650-Watt 80 Plus Bronze Certified Power CMPSU-650TXV2 $69
case Antec Three Hundred Gaming Case External 3 X 5.25 $45
ram Corsair Vengeance 8 GB ( 2 x 4 GB ) DDR3 1600 MHz (PC3 12800) $50
ssd Crucial 128 GB m4 2.5-Inch Solid State Drive SATA 6Gb/s CT128M4SSD2 $198

All these put together come up to $900 before tax or anything..
I had no idea performance vs price for each part. But, I've been heard that i7-2600k with overclocking and hyper-threading is helpful a lot in reducing quite amount of time in computing and coding. Any comment and suggestion would be meaningful a lot to me. Thank you

LOL.. well i read "laptop" in your question but i'm guessing this is actually a desktop..

The 2600k is a great processor and if you are OC'n it, i would recomend Corsairs H100 water cooling. It may get a little hot :) 

You might want to look into the i5 2500k.. It is a taaad bit slower than the 2600k, but will save you 100 bucks and still give GREAT performance for what you are doing.

woops, what am i thinking? it's of course a desktop what I have in mind. Thank u for your advise. BTW, I heard that the only significant difference b/w i7 2600k and i5 2500k lies in hyper-threading. it it true? I'm good to go with i5 enjoying price cut?

I think you should get the 2600K as it is much faster for coding and the Antec 300 is not my favorate case you might want to look up the Corsair 400R. =)

yea, the only advantage of the 2600k is that it supports hyper-threading. Even though I use VS20xx daily I don't know if it takes advantage of hyper-threading. Never bothered to look into it.

(Exception to the below if you are intending to use linux since NVidia is best supported)
I question if you need the graphics card though. Unless you are doing serious 3D programming (which it doesn't sound like you are) the HD3000 graphics should be able to handle everything you need (including 3D graphics in Matlab). You could get a Z based motherboard and use the integrated graphics and overclock. The ASRock Z68 Extreme3 Gen3 is $125 and supports overclocking and integrated graphics. There might be some other good Z68 boards for cheaper, but I'm yet to find any.

With or without the graphics card you don't need a 650W PSU. The CPU will take ~130W and the graphics card you chose is 50W. You could get away with a 300W PSU, but not a lot of brands make quality 300W PSUs. To get 80% efficiency you need to have at least 20% load, and you'll probably be sitting well below 100W at idle which is below the 20% mark for the 650W PSU. You could get a Corsair CX430V2 (only note is that it has a 30C rating, but I know it has been tested up to 50C with no problems), or you could get an Antec EarthWatts 380. Both are around $40.

Personally, I wouldn't blow an extra $100 on the 2600k. I use VS2010 everyday with my work laptop on the first generation of i5, and i occasionally use it on my home PC with the 2500k. Between those two, I don't even see a performance difference when it comes to compiling. I could see it having a benefit if you are constantly compiling extremely large programs, but nothing that constitutes $100.

seems 2600k wouldn't be that beneficial given the price. Thanks a lot

plus.. you can always OC the 2500 to the speed of the 2600 if not more :) ..

Could you possibly recommend a decent non-expensive case as well? ^^

I don't typically care to suggest cases because they are mostly chosen on looks. I suggest any mid-tower case that can hold a 120mm fan in the back, and at least 80mm fans in the top and front (preferably 120mm sizes for a quieter case). PSU top or bottom hardly matters to me especially on this build.

If the 120mm rear fan is next to the rear io panel the case should be wide enough to hold the Cooler Master Hyper 212 Plus, but always double check. For example, the Antec One Hundred suggested below has two newegg reviews. One person says it fits, the other says it doesn't. I believe the guy that actually put it in, I think the other guy just guessed.

A few examples:
Antec One Hundred (cheapest at $35 after rebate) - http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Antec Three Hundred would work
Cooler Master HAF 912 - http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Personally I'm partial to the HAF 912 myself, but never bought one because I have a Apevia Cruiser from 6 years ago back when they were called Aspire.

My opinion on cases is to get one with as little air vents and mesh as possible..
For a few reasons

1. Mesh attracts dust like no other
2. You want to keep positive pressure in the case than in the room. By doing this, you lower the amount of dust in your system and keep the air flowing where you want it to go (in the front, out the back or from the bottom to the top). With Vents, mesh and random holes in the case, you get dead spots where air doesnt move correctly and some parts of your mobo or video card heat up and/or collect dust.

a great idea for a case is the Corsair Obsidian

Thank you so much for all valuable words
Corsair Obsidian looks perfect but kind of beyond my budget :( 
I might need to stick with antec 300

If you want to know if Hyper-threading would be worth it, just google whatever software you use most and see. A lot of software vendors will tell you.
