I can see your new here, so let me help clarify a few things before you blow all that cash lol. A single 7950 GX2 card is two cards in one, basically SLI out the box. However, right now you cannot SLI two 7950's to get Quad SLI, Nvidia doesnt support it officially for consumers yet. Right now based on benchmarks any 7900 GTX SLI combo (standard and overclocked) are still the fastest setup beating even the 7950. However, once Quad SLI is supported it will blow those 7900 out of the water. If you have the money, go with one 7950 for now, then buy a second because you can't use two together yet. As for Quad SLI, no one knows when Nvidia will release the driver to enable it, but rumors claim the end of the month and end of summer a the latest.

What about the Dell XPS 700 Build Your Own package?
They advertise they will sell you a 1KW powersupply, 512MB of ram, Motherboard, and intel processor already installed and you can also customize it to have them give you dual 7950 GX2 Cards pre installed on an SLI config. Its expensive though.

Nvidia partnered with dell to first bring Quad SLI to life, right now only official system builders get the Quad SLI drivers. Here's the official quote from Nvidia: "Quad SLI technology enabled through select System Builders delivers SLI support for four GPUs, providing mind-blowing performance and image quality at extreme resolutions. SLI support for the GeForce 7950 GX2 will be provided through a future NVIDIA ForceWare driver release. See www.slizone.com for details"

Problem is those other system manufactuars charge a crap load for Quad SLI. Dells XPS Renegade that first had Quad runs for $13,000, and chances are if you add that support to that XPS 700 the price is gonna go nuts. I'ts be much cheaper to just wait for Nvidia to officially suppurt Quad SLI and pay $1200 for it as oppossed to those ridiculous Dell prices.

What kind of cooling would you need?
Right now I have 2 120mm Aspire LED Fans and 2 80mm Aspire LED Fans and the standard AMD heatsink and fan combo.
Would I need to upgrade anything else besides getting a 1KW watt power supply?

You'd be fine, but it never hurts to add more fans for cooling, and that power supply certainly has enough juice to go around. If your considering running Quad SLI, you might want to overclock your CPU as 4 gpu's can really be stressful to that single core cpu. Def might want to go Dual Core for Quad SLI. If your gonna overclock do NOT use that standard heatsink/fan and while those fans are nice, what really matter is how much CFM they're putting out. What does your overall system temperature usually idle at?

Im tyring to build a system plan and I liked the XPS 700 Case but I wanted the AMD motherboard and I didnt want to pay over 1,000 dollars just for the powersupply and case when im going to get rid of the other stuff. Would you go with Intel or AMD at this point becuase of the new Core Duo 2 Extreme?

Honestly, right now I'd stick with the AMD FX 60 or 62 since they're both Dual Core. However a nice Pentium D 955 EE would also work rather nicely with Quad SLI. The highly anticipated Conroe from Intel is what all gamers want, but it won't be available until July. So if you can wait it out, I'd def go with a Asus Conroe board and Conroe cpu. If you can't wait, I'd go with an AM2 AMD FX62.

Quad-sli is working but it's risky since it's not supported yet. I just starting using quad-sli a little while ago so I haven't gotten a chance to test it a lot yet. Heh, currently I'm running it with a 480W power supply but that's not recommended either. :)

See the below thread to see how things have been with jakUp's quad-sli system. There are also a couple of review sites that had success testing quad-sli (some didn't have any luck testing it). I'll find the links and post them here in a second. I think at least one of them compared it against 7900 GTX SLI.

Here is one site that had luck testing it:

Here is another:

Just be aware that everything may not work properly just yet if you decide to jump on it at this point.
