It is time to rebuild my desktop ~5 years old
I'm not a "techie" and I don't keep up with hardware advances between builds, but I do write software and I feel obliged to build my own machine
Probably going to replace just about everything except the case(Lian Li server case) and the speakers.
I am not a "Gamer" -- lots of video though
Will have Two Monitors -- A 22" mitsubishi crt and a flat screen that is yet to be determined
This is what I have chosen so far:
ASUS RAMPAGE FORMULA LGA 775 Intel X48 ATX Intel Motherboard
Things have changed in the PSU area. Your choice is really overkill. Even if you are buying to last 10 years. For a single video card build get the Corsair 750TX (still overkill but I know you want no less). If you want a crossfire PSU get the Corsair 1000W.
The only time 1200W would make sense is with quad SLI.
Get a 1GB 4870 instead of the GTX260. If you did decide you needed a second card in the future, you could add it to your crossfire board that way.
On the board... it's really overkill for you as well. It's a great board for a gamer running crossfire. You would be just as happy with a P5Q -E... great MB cooling, eSATA, firewire, RAID. All the features you need, just not a high end gamer board. You could even spend less and get a P5QL -E. The P5Q -E would accomodate a second video card also, if you felt the need... it just wouldn't have as good frame rates in games.
RAM: You don't need 1066Mhz. It will make no difference, and indeed you will not use it at all. the only time you need 1066 is if you push the front side bus past 400Mhz... which I doubt you want to do.
You actually only NEED 667Mhz RAM. However, it's best to get 800Mhz because of the price and because you never know... maybe in 5 years your poor cousin will want to buy your system and OC it a bit to get a year or two out of it.
