600-700$ build (critizie if needed)

Intel i3 would be MUCH better. Go with a 6850. Why the Z77 motherboard? It's really pricey. Try for an H61, and it'll be way less expensive (which you can use to get a 6870 MSI Twin Frozr II OC GPU).

However, you seem to have an i5-2500k picked out. If you are going to overclock, then get a CPU cooler (Hyper 212 Evo), a Z68 Extreme3 Gen3 from ASRock (or a Pro3 Gen3), and the i5-2500k.

HDD has a small cache, but it's not horrific.

Change the link on the PSU... it shows that it added to cart, but it's misleading because of the Corsair 400R underneath it. PSU is fine, though.

I'd really go for a 6850 or 6870 if you're gaming. 7850 would be GREAT (GTX 560 Ti is really close to it).
 
An I3 or an AMD phenom II would not be better than an I5-2500k. Good processor, good mobo, PSU is fine for that GPU, but anything much more powerful and I'd be looking for a slightly larger PSU. If You're building it primarily for gaming, get a better GPU and PSU.
 
I'd go ahead and save yourself $5 for exactly the same hard drive by getting it from Newegg instead of Tiger Direct:

You also might as well get an HD 6850 as your GPU for the same price as that HD 6770:

For another $10, you could get a power supply that would allow you to add a second HD 6850 later if you ever wanted to:

Long-term, I would probably recommend crossfired 6850s; a single one will be ok for now, but it will be the bottleneck compared to your CPU.
 
OK, but if you want to avoid spending more money for inferior parts, you'll use them anyway for those. If you take some principled stand, 1) nobody is going to notice it, and 2) you'll just end up costing yourself money. I'm sorry you had a run of bad luck, but you're not going to drive Newegg out of business, so don't shoot yourself in the foot. I've generally found them to be better than Tiger Direct on price and reliability anyway.
 


Most people would say that about Newegg vs TigerDirect. Check resellerratings.com for the proof.
 
Also forgot to mentioned 6850 is like $10 more so just get it. Also I would recommend at least 650W PSU. It is better in a sense that it will not work as hard as 430W PSU. So let's say your total system drain under load is 350W so that is 82% load with 430W PSU...when you have 650W the load is 54%...so I hope you got the point...less work=less heat=longer lasting product and of cause better efficiency at lower loads.
 
^Agree on 6850, disagree on 650W. Do a quick PSU check on eXtreme Lite PSU calculator. However, if it's going at more than 80% efficiency, that's not good. 20%-80% average load is ideal.

Now a 550W would be nice, as well. 500W?
 


It is so simple man. If you have 2 engines one running at 8000RPM and one running at 5000RPM which one do you thing burns first? Same thing with PSU. The best part is that
650W PSU is less expensive than 550W.

here is example

few days back 650W was for $59.99

I know that 500 or 550W would work but they will work harder which is what we don't want.
 
Do you know how PSUs work? They don't exactly have any moving parts... except for the fan. The only way they do age is through capacitor aging, which is so small that it is almost insignificant. I accounted for that on the calculator with a whopping 25% aging.

I agree that if a 650W is cheaper, you should get it. You should ideally try to stay within 20% to 80% of full load to achieve maximum efficiency. But if it's between, say, a silver rated 550W and a bronze rated 650W, get the 550W.
 


Dude I know...engine was only an example that everybody can rely to...I don't think he would understand if I'd said that realignment of the electrical dipoles within the capacitor, which is affected by time, temperature, and voltage, would help much ... the facts are that the less load PSU has the better = slower degradation.
Yes more efficient PSU the better but platinum PSU are expensive. The price you pay for 500 or 550W just pay little more to get 650 or higher $10-$20 more won't matter...just get a good quality stuff
I'm running Antec 1000W TruePower Quattro have it since 2007. Do I need 1000W? not at all. I changed so many MB and GPU only thing that I reuse is my PSU. For its age it it is up to 85% efficient which by today's standards it would be certified as gold.

Anyway I had Antec Neo 520W once and it failed me twice...I ran SLI on it and it just killed the PSU because the load was too close to its limit. The PSU lasted less than 1 year...so I just RMAed it and sold replacemend on ebay and bought 1000W since then I have zero issues. I'm off the subject sorry :)
