the monitor will be the same one for both systems as well as the sound card

as u could see on AMD i still dont know to which mobo should i go with :( 
the cpu cooler is not a big deal for me(i can afford both of them)
and my other issue is with the video card selection, both systems are for CFX(CrossFireX) and gaming(of course) but its kinda hard to choose a video card as ther a looooooooot of them out there with excellent results doing CFX wich gets me more confused :??: 
one more thing that i would like to know if that i should go with SLI or CFX, which is cheaper and gets the best results.....btw im talking bout ~$900 maybe less budget

any help will be well appreciated....thanks to any1

EDIT: sorry bout that, one more thing im thinking maybe on water cooling as well....what would u say???

You shouldn't build the Intel system. The LGA775 socket is a dead socket. You won't see anything new for it.

Watercooling is pointless. You can get quieter, cooler solutions using air. It'll also destroy your budget.

Crossfire isn't something you do when you first build the system. It's an upgrade option.

Do you not need a hard drive or an optical? What about an OS?

Given $900, here's what I would build (assuming you need nothing but the pieces you've listed):

CPU: Phenom II X4 955 $166
Mobo/PSU: Asus M4A79XTD EVO and OCZ ModXStream 700W 80+ Certified Combo for $156 after rebates
RAM: G.Skill Ripjaws 2x2 GB 1600 mhz CAS Latency 7 $115
Cooler: Coolermaster Hyper 212 $30. Cheap and one of the best.
Case: HAF 922 $110. Bigger than the Antec.
GPU: HD 5850 $290

Total: $866.

This would be a great gaming machine, and certainly would destroy either of the above.

thanks a lot madadmiral....i have another question, ive a friend wich is running this
Intel Core i7 920, Gigabyte GA-EX58-UD3R, 6GB(3x2GB)GSkill 1333 sdram with a coolermaster V8 and a poor 1gb GeForce 9500 gt, but it looks like the mobo is not recognizing 2 of the 3 rams, he has done everythng to it and nothing works so i think the 2 slots are dead so his planning on changing the mobo...he should also change the PSU and the video card in order to get a good gaming pc? is there anyway to fix those ram slots?
thanks again to everyone

Has he rotated the RAM sticks? In other words, did he take the working stick and put it into the other slots. Or try booting from each of the sticks in the same slot? I would download MemTest86+ and run it over night to test the RAM.

I doubt it's the board's fault. It's more likely that the RAM is bad. However, if the board is bad, there is no way to fix it.

If you're asking about what he should upgrade, that GPU has to go. It's basically an ancient card. As far as the PSU, I have no idea because you didn't list it.

the ram sticks work perfect all of them but it just boot from the first one and also nor everest and the system info recognize all of them(just 1) we rotate them we tried'em on another pc and they work so...

well sorry bout the PSU but ive never seen that PSU not even in newegg so i just dont have idea where did he buy it from or the brand and bout the GPU i told him to go with some good ATi cards(2) and go with CFX....btw should he change his CPU cooler as well while getting CFX or that V8 will be good for that purpose?

The V8 should be fine.

If the PSU isn't listed on Newegg, I highly doubt it's a quality unit. If he can afford it, he should think about getting a quality one. I'd stick to Corsair, OCZ, Antec Earthwatts, FSP or SeaSonic to ensure quality. Make sure it is at least 80 Plus Certified or higher.

I also wouldn't get 2 ATI cards. Buy the most expensive 5xxx series card you can afford, starting at the HD 5770 for $155. Crossfire is meant to be a cheap potential upgrade option, not a starting option.

Air by far. Water cooling can be a lot louder and doesn't typically get you any cooler. In addition, there is always the chance to spring a leak and lose the entire build.

i told him to go with the Corsair CMPSU-750TX 750W which is SLI and CFX ready and 80 Plus Certified and its cheap as well and bout the card well that is all up to him if he wants to play bad**s games but the 5xxx series are good ones.

oo good news..he's here reading everything lol :D ....hi madadmiral lol, hey i wanted to ask u bout the mobo im planning to get, i got the ASUS P6X58D Premium LGA 1366 Intel X58 SATA 6Gb/s USB 3.0 ATX or ASUS P6T Deluxe V2 LGA 1366 Intel X58 ATX the prices are almost the same but it seems that the Deluxe has more potential and also better reviews than the Premium one...whachu say?

First, don't trust user reviews. Most of the authors shouldn't be allowed near any piece of technology.

Second, the Premium is a better choice. The main differences is that the Premium has USB 3/SATA III support, making it more future proof, while the Deluxe has an extra PCIe 2.0 slot. The problem with having 3 PCIe slots is that Crossfire only scales well up to two cards. Anything above that doesn't give very good performance gains and is a waste of money. Thus, boards that have 3 PCIe slots are a waste of the premium paid to get that third slot.
