not sure if i need anything else or if i should change a part to make it cheaper or make PC faster. so far with part build is at $1034 give or take without windows.
I also don't know what i have to buy to make pc windows vista premium 64 bit like my old computer because it was a gateway. Can i just use recovery disk on this pc cause i got two sets of them from old pc. and tips for build

thanks for all the help

Get rid of that Xion. You can't use a Gateway recovery disk.

Do you plan on using 4 Video cards? If not that motherboard is over kill. I am using one to build my first farming rig and even though I think it is a solid motherboard, the company themselves leave little to be desired when it comes to tech support and RMA. I highly recommend you go with an Asus motherboard.
Power Supply all you need is a Corsair 650W to run this rig, as GLC suggested dump that Xion it more than likely wont last a month.

ok will get better PSU but want a 1000w so that in the future like ,1 year ,i can run 2 4870x2 and will change my motherboard to an Asus that has crossfire ready. for the operating system does windows vista come with both 32 bit and 64 bit on one dvd or they sell them diffrent or can i go to a PC store and let them upload the OS for cheaper than its going to coast me?

Here is a great deal on a 1000W PSU http://www.newegg.com/Product/Produc...82E16817371012

If you want to run two 4870x2's, buy only a certified PSU.

You have to click on "Details" on each one and see if it supports 2 cards. The Antec that Khalil linked does. So does a Corsair TX750.

I would take the Corsair over the 1000W Antec but OP wanted a 1k PSU

My friend told me that i am waisting money on getting DDR3 memory and should just go with DDR2 because he said they do the same thing at the same rate.He also told me to get AMD Phenom II X4 940 Deneb 3.0GHz and overclock it and it will run better than the AMD Phenom II X4 955 Black Edition and i would save a total of 200 dollars.

[Khalil]

It is a good idea to go with the 940 and save $200 but it is not better, for the money though your friend is right the 940 is the way to go.

If you want DDR2 you will need a different motherboard.
