2 ati cards as my boys games play best on them
and a 1200w as it may need at high rate processing.
o/s window 7 home premium


I think that 1200 watt power supply is a bit overkill..
As I have 2 GTX-260's and a 650 watt, is plenty.
It also powers 3 hard drives, 2 DVD burners and multiple fans.
And yes I am a gamer as well.


Well if he is thinking of expanding to 4 video cards then 1200 watts might not be enough. They proved with 4 X GTX480's that you need almost 1600 watts to run them. My 2 in Furmark have hit 905 watts so his estimates are not bad. I don't like running my power supplies at 100%, 75% is much easier on them and then you don't have to worry about loud fans as a nice side benefit.

Then only the Silverstone 1500w psu would do, But last I looked It's only certified for 3 GTX480 cards, Me I'm going to get a 1200w psu, But then I'm not interested in a GTX480... I have a GTX295 and I intend to get 2 more GTX295 v2 cards.

As a side note:

Recommended Power Supply

So here's my power supply recommendation:

GeForce GTX 295

* A GeForce GTX 295 requires you to have a 700 Watt power supply unit at minimum if you use it in a high-end system. That power supply needs to have (in total accumulated) at least 50 Amps available on the 12 volts rails.

GeForce GTX 295 Quad SLI

* A second GeForce GTX 295 requires you to add another 300 Watts. You need a 1000 Watt power supply unit if you use it in a high-end system. That power supply needs to have (in total accumulated) at least 70 Amps available on the 12 volts rails.

Ok I fixed Your link and made It active for other users and I have an Enermax 1050w psu and I've run 2 GTX295 cards off of It 24/7 with no psu problems, The GTX295 uses 288w or 24A and 3 cards should use 76A at stock speed, But then I don't overclock the video cards, Just the fans, I run them at 100%. I'm going to get the Corsair 1200AX psu, It has just over 100A on the 12v rail.

Yeah, you know review sites, they use very conservative marks just like the manufacturers.

What to look for in motherbroads. I am going to build a pc intel i7 980 but cannot find info on good motherboards, it will have 2 ati graphics cards and main use games,cruching,and a little home work.
It will be my first build i am very new to computers.
Motherboards are the only thing that i can not lots of info on, but i have a feeling that its an important decision.


You might want to look over some of the articles at toms hardware.
http://www.tomshardware.com/reviews/Components,1/Motherboards,2

They have done comparisons between things like the 900 series & 800 series i7 boards with multi video cards. To find out at what point the 900 series' increased bandwidth actually start to matter. I am not in AMD systems myself, but they have topics about them as well.

Based of their, and several other peoples, test results between the two i7 series I went with the i7-860 for my newest system back in Jan. As I wasn't going to be building a 3 or 4 GPU uber gaming system the 900 series was just extra money in my situation.
