That's a great PSU choice. http://www.newegg.com/Product/Product.aspx?Item=N82E16817702008 is comparable and $10 cheaper, if you're worried about cost.DarthHK said:

the ONLY reason anyone should even consider using ln2 is if your going for an overclocking record. ln2 is NOT sustainable for 24/7 use. if you want the absolute best overclock that is 24/7 sustainable your looking at liquid cooling, but honestly air coolers like the TRUE (thermalright ultra-120 extreme) can net you a very good overclock without the cost of building a liquid cooling system and air coolers only need occasional dust offs, whereas liquid systems require constand cleaning which require you to take the whole system apart, they are much higher mateience. but yes, overclocking a lower end cpu to the levels of a higher end one offers the same performance at a much better price, you just have to be careful when overclocking espically if your using a core i7.Sewblon said:
Don't I know it. A year ago my sister's PC got lots of dust stuck in the fan, which led to the graphics card getting fried. Took a week (for my father) to fix. Incidentally it's the one I'm using right now as I'm worrying about my current one.megapenguinx said:
i am not certain that a 650 is necessary for a single 9800 gtx. If you have any intention of dual carding, i would certainly say you need it, but for an air cooled, dual core
Even a 550 would be fine. I have a 1000 W behemoth on mine waiting til I find 1000 in the street for two 295s in quad sli that I want but certainly do not need.
Watch off brands; aftermarket PSUs are actually very common failure sites. a corsair brand PSU is pricey, but that thing is a rock with a wonderful mfg warrenty. thermaltake is another quality, but expensive, brand.

for suicide-run benchmarking of a new chip, yes, yes they might need it. I've got my i7 overclocked to 3.8 ghz on air with an aftermarket cooler, so as long as you don't go psychotic there is no need for anythign like ln2.Sewblon said:
Yeah, another vote for a decent PSU, just in case you are not convinced.
Sure it's possibly the most dull part of making a PC, but in many ways the most important and it doesn't cost a bomb to get a good one.
After all it's the difference between maybe $40 and $100 for a PSU, or $40 and $700 for a video card, and I imagine the PSU will have a longer upgrade lifespan. The only time I ever had to upgrade one was when I moved from IDE to SATA hard drives and my old PSU didn't have the correct cables.

Wow lots of useless advice in this thread.
- First PSU lots of people have given the standards. Go for a Brand name PSU. Corsair are sweet as are Seasonic, (Corsair are rebranded Seasonics.) I run a 260GTX off my 520W Corsair without issue. Wattage is a factor but you also have to have a decent Amperage on each of the PSU Rails. That Corsair, as with all Corsair, has only one rail but it's got a good 42Amp on it so that will be more than enough to run a 9800.
- You've had two people mention that Quads are better than Duals and the higher the clock speed the better. Both are wrong. If the program is optimised to take advantage of multi core CPUs then yes it will be faster otherwise you won't notice a difference. More and more games are starting to appear with Quad Core optimisation but unless you do serious encoding of videos or rendering then I doubt you will see any noticeable difference in day to day use. As for the higher the clockspeed the better argument; what wins in a straight fight a 3.0GHZ Pentium, 2.6GHZ Core 2 Duo or a 2.4GHZ Core I7? Clock speed can only be used to determine power within a singular range of chips the days of using clockspeed to work out how powerful your CPU is compared to everyone else has long since passed.
- ESD; you would have to be stupid beyond belief for ESD to damage a harddrive. The HD is encased within a metallic box which acts as a Faraday cage, you would need an electrical charge way way beyond anything you could generate through static to damage a harddrive.
ESD charge typically destroys the transistor gates within the memory and CPU ICs. The transistor gates in these components use fractions of a voltage to operate and a typical ESD discharge can be thousands of times greater than this. To avoid this a simple ESD anti static wrist strap attached to the PC case whilst the PC is plugged in but switched off will do the job. When you remove any components you can generally lay them on the anti static bag the component came in or even that a clean proper wooden table will do the job.
- Dust; will not kill your computer. Infact chances are you are more likely to kill your computer by removing the dust with a hover or by blowing on it than you are from just leaving it. Dust does clog fans and can cause over heating but the amount of dust you would need to do this would require the life time of the computer to build up. Dust is also not combustable. Well more correctly if you have anything inside your computer that is hot enough to ignite dust then you got bigger problems than the dust itself.
If however you do have an uncontrollable need to clean something that doesn't need to be cleaned then use a can of compressed air.
