I'm building a computer with these parts which all but the video cards have arrived...

my question is what positions do i have to put these cards in so they all fit, with still using SLI connector for the two cards?

8800GTX uses PCIe + slot directly below
Tv Tuner uses PCI x1 slot
sound card uses PCI slot

please give me possible combos of how it should be setup please, if there is more then one. Also i'm a new builder so might have to explain it a bit more then to the regular builders.

You'll never be able to fit all those on that board, you can use three of the four but all four won't work.

I looked around but I couldn't find a single slot cooler for the GTX, I think the only way you would be able to do it would be to water cool 1 or both of the GTX's which would open up your extra slots.

what if i tried something like this?

for the flexible SLI bridges will any of them work...

1) ASUS NVidia SLI Bridge
- Appoximately 2-3/4 inches (70mm) from center of each connector.
- Approximately 3-1/8 inches (80mm) end-to-end.

2) ASUS NVidia SLI Bridge (LONG)
- Appoximately 3-7/16 inches (87mm) from center of each connector.
- Approximately 3-7/8 inches (100mm) end-to-end.

3) MSI NVidia SLI Bridge
Length: 3.75 Inch ( between the two SLI connector )

if i can get one of these connectors to work ... if it flexes high enough to clear the sound card, and tv tuner, while still reaching the SLI connectors on the GPU's)

will my setup look like this on the board?

[CPU END]

[PCIe 1] - |8800 GTX|
[PCI x1] - |Duel Slot|

[PCIe 2] - |Sound Card|

[ PCI 1 ] - |Tv Tuner|

[PCIe 3] - |8800 GTX|
[ PCI 2 ] - |Duel Slot|

Even though PCIe x16 is meant for the 16 pin cards i read somewhere all are backwards compatible meaning they can support x8, x4 ,and x2. The same goes for the PCI x1 Tv tuner it should be able to be able to use the PCI x8 slot shouldnt it?

by the way all of those SLI bridges were found on ebay... if you want to check them out

All SLI motherboards come with SLI connectors and the one that comes with the board will be fine. the problem is the sound card you picked is PCI not PCI-E, they are not compatable. You could put the video cards in two of the three 16x slots but either way you do it you would loose one slot you need which is why I said you can only use three of the four cards. Something like this would work http://www.ncix.com/products/index [...] ive%20Labs
You can use a 1x card in a 16x slot you just have to be careful and be sure you get it in correctly.
