[tyler387]

Coolermaster HAF 922 case

lite-on 24x dvd writer

500gb 7200rpm 3gb/s hd

sapphire radeon hd 5770 1gb ddr5

gskill ripjaw 4gb ddr3-1600 memory

x2 cold cathode lights 12"

ASUS P7P55D LGA 1156 Intel P55 ATX Intel Motherboard

intel i5-750 2.66ghz (i want to overclock this to 4.0ghz stable)

extra 120mm case fan



what kind of power supply do i need, like how many watts? and what brand? i heard corsair is the best.

also, what is the best heatsink i can get to run this i5-750 at 4.0 ghz stable? (i would play WoW many hours at a time, nerd huh? )

Corsairs are very good - although perhaps not the best. Having said that, I use Corsairs. The Corsair 550VX (41 amp 12 volt rail):

would work nicely.

The best heatsink would use water cooling. This one is starting to get really popular: COOLER MASTER Hyper 212 Plus

I have a couple of these:
Xigmatec Dark Knight

But you would need to buy an LGA1156 bracket for it - about $8 from newegg.

If you intend to add a second 5770 then you might want a bit more power.

Best:
Seasonic X650 http://www.newegg.com/Product/Product.aspx?Item=N82E16817151088

Very good:
Corsair HX650 http://www.newegg.com/Product/Product.aspx?Item=N82E16817139012
Antec TP-650 http://www.newegg.com/Product/Product.aspx?Item=N82E16817371021&Tpk=TP-650

1) what kind of power supply do i need, like how many watts? and what brand? i heard corsair is the best.

2) what is the best heatsink i can get to run this i5-750 at 4.0 ghz stable? (i would play WoW many hours at a time, nerd huh? )

1) I consider Corsair, PCP&C, Seasonic, Enermax, OCZ and the Antec Earthwatts line to be the best PSU's available.
With your setup, I would recommend a minimum of a 450w PSU and AMD Recommends a 600w+ PSU if you plan on CrossFireing your 5770 in the future.

2) FrostyTech has a good listing of the Top 10 CPU Coolers which would probably be a good place to start.
JSC has a few good ones listed, you will probably need to list your budget so we can narrow it down a little more.
If you have the budget and some extra time to set it up, water cooling is an excellent alternative.
Swiftech makes a great kit to get you started, currently $230 on Newegg.
