Can anyone make a recommendation of good amount of watts necessary for this setup
q9550
9600 gt (possibly gtx260)
Western Digital Caviar Green WD5000CSRTL 500GB 7200 RPM SATA 3.0Gb/s 3.5" Hard Drive
GIGABYTE GA-EP45-UD3L
Gskill 4gb ram ddr2

More about : recommended watts psu

With a GTX260 you need 500 watts. You only need 400w with a 9600GT. Get a good quality unit from Corsair, Antec, PC Power and Cooling or Seasonic and you will have no problems.

If it's a high quality PSU (+80% efficient) with good 12V rails boasting good amps, then 400 Watts is enough for that system. I have the same CPU, 1 GTX 260 + 1 8800GT as dedicated PhysX card. Under full load (measured at power outlet) my system consumes around 380Watts, that's with two graphics cards, mobo, cpu, 2 harddisks and 3 120mm casefans.

I guess a good 500 watt PSU should keep your rig powered and silent.. The corsair VX 550 or the antec TP 550 should do perfectly..

You have any good recommendations on for a PSU?
Which do you use?

Anymore specific PSUs will help a lot. Thanks.

That Corsair is an excellent unit and is plenty of power for what you listed. This is another good choice especially for the price and gives you quite a bit of upgrade room: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

I hope you are not using that WD Green for your C: drive. Those Greens make great storage drives but they are slow. If you have not bought it yet get a Samsung Spinpoint F3 500GB or 1TB. You will be much happier.

I'll check into that PSU aswell
Also
The only option I have for the Samsung Spinpoint F3 500GB is a bare drive. Are there any cables I might be missing when buying just a bare drive?

Here's the current build im looking into with the exception of the HDD you stated.

Well to be honest I would not build an LGA 775 based computer. It is really dead tech at this point. Especially with that 9550 that is OVERPRICED. You do realize you could build an i5 750 system for almost the same price?

Core2Quad $279???

i5 750 $199

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Gigabyte MB with USB 3.0 and SATA 3 ( much more futureproof ) $129

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

GSkill DDR3 1600 cas 7 same price $109

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

MUCH faster video card $175

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Get the Antec PSU I listed and you are good to upgrade your video card to whatever you want if you need to.
This will DESTROY the build you had listed.

Edit: throw in one of these for overclocking: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

I know that the total is less than $100 over your orignal budget.

The motherboard will come with the SATA cables you need for a barebones hard drive.

I got the q9550 for free so that's why it would be the ideal build...I think. Also I've heard mixed opinions about building a 775 or going for the new i5/i7 to the point where it's half and half.

The free Q9550 almost makes it worth it to go with LGA775. I would just drop it in my motherboard if someone gave me one.....but if I had to buy everything else as well I might just sell the Q9550 and go with an i5 750. DDR3 that is twice as fast as DDR2 is the same price....the P55 motherboards support USB 3 and SATA 3.....the list goes on. That Q9550 was awesome in 2008 but that is like 50 years ago as far as tech goes.

As to the 50/50 mixed opinions I have to say the 50% who told you to go LGA775 have no idea what they are talking about lol. LGA775 is basically obsolete from a new build standpoint.

Oh well the it is up to you and what you can afford.

I think the 50 would be people who already own a Q9550 telling themselves a i5/7 build isn't really worth it! If you have a free 9550 you could sell it and use the cash for a new build. Depends how much stuff you've already got, money, and if you don't mind buying bits second hand.
If it was me (as mainly a gamer) I'd get a 775 DDR3 mobo off fleabay for probably half the price of a new 1156 board, get me 4gb of DDR3 1600 for the cheapest i could, and then buy a new PSU, and spend whatever extra I'd saved on the mobo and CPU swap to go in for a better gfx card. Although I'd proabably spend some of it on a decent cpu cooler, clock the Q9550 up to 3.4 and get a HD5770 and stick the rest of the ££s back in my pocket!

The first thing I decided my build a month ago was having a ddr3 motherboard but I decided to change it. Now I might just go back.

I personally don't see DDR3 to be any speedier as compared to DDR2 with those high latency timings.. May be good for overclocking and will give a little higher memory bandwidth.. All in all, good for synthetic scoring but real world apps show very less benefits if any..

P.S. - The Q9550 has enough grunt to keep your computing needs satisfied for another year or so.. That also suggests You'll get instant cash once (and if) you decide to sell.. Now as i understand, the point in selling it would be the dead LGA775 socket in which case, the LGA 1156 and 1366 are also nearing termination.. So your best bet would be to go with the AM3 to ensure a relatively longer stay with your build..

How much longer until most games/applications actually use the full power of a quad core, much less a i7?

It all depends on the programmers.. Coding is a tough job and it gets tougher if core optimization has to be dealt with.. My idea is that it'll not come in full swing until quad cores become the norm even with desktop apps.. May be win 8 will be the time.. Lets see..

Wait.....what? Most new games and new programs DO make full use of quad cores. If they did not then i7 would not be the fastest thing out there. Look at any of the benchmarks......i7 is faster at everything. Windows 7 x64 has support for 256 core processors!
Now the Q9550 is by no means slow. It is a bit faster clock for clock than any AMD quad. If you can overclock it to 3.4-3.6ghz then it is about as fast as an i5/i7 stock.
DDR3 IS faster and latencies have come down quite a bit since it was new. You can get 4gb DDR3 1600 cas 7 for ~$110. Core2 can not use that extra bandwidth like i5/i7 can though.
June 30, 2010 2:09:17 PM

If you stick with the Q9550, then still go for DDR3. You will get better flexibility with overclocking and you may well be able to use the RAM again in another build further down the line which you definitely won't with DDR2.
As anort says many games do now make use of 3-4 cores. All X-box ports will use 3 cores, and pretty much all games coming out from now on will use 3 or more cores. So Triple/Quad core gaming is most definitely here, no-one should get a dual core of any generation for gaming!
