Okay, I have one of these and plan on getting another to run a dual card setup (and yes i do have the power supply to run it, im getting this one), but i have a few questions. One: How do i set it up? do i need to install the drivers again or just set it to run in sli mode in the nvidia toolbar thingy and turn off the comp and put the stuff in(ie. card, 2 card connector and the thing to keep it in place.)? I really want to get the card and PSU for christmas so i would like to know asap. And Two: Can you overclock 2 graphics cards? I know how to overclock one, but 2, im not sure. Thanks

Here you will need this to help you get your foot out of the back of your throat, looks llike its in there pretty deep. And what is that on your face? Egg?! *hands Kim a washcloth*

that powersupply is CRAP. get an antec at the very least. if you want to run SLI read your mobo's manual to see how to enable it on that particular board. when you get to windows there should be an option in the drivers to run dual cards, or to run SLI.

For SLI, I wouldn't get anything less than 500 or 520W.

Try to find one that is SLI-rated or SLI-Ready.

You need to get an SLI motherboard because I think that's the only way to get the connector.

Okay, i have this mobo so i know i can support dual cards. Is this power supply good enough? its 500w and can support SLI and ATI cross fire.

HaloKing, please take a visit to the Nvidia certified hardware page. If you are unsure what makes for a good SLI powersupply, which it looks like you are, then this list will be invaluable. The last thing you want is a PS that can't keep up with your system.

Unless you have one of the more recent motherboards, there is usually something you must physically do to your motherboard to make it ready for SLI (on mine you have to flip around a special SLI chip to enable SLI mode). While we're talking about motherboards, usually your SLI-ready motherboard comes with the bridge that connects the two video cards once they are installed.

It would not hurt to uninstall your existing graphics card in Windows right before you shut down to install your new one. You should make sure you have the latest drivers to ensure a smooth SLI experience, otherwise you will likely run into problems. Have the latest Nvidia drivers sitting on your Desktop for when you boot back into Windows. Windows will tell you that it has found new hardware when you boot up. Cancel out of that screen (it'll pop up twice, naturally), then double click on the driver install EXE. Once it is done installing, you'll notice a little bubble pop up in your task bar that says something to the effect of, "This system is ready to take advantage of SLI." Click on it and it will take you to the Nvidia SLI settings page, where it's a matter of clicking on a little radio button to enable SLI.

Back before Nvidia updated their drivers, you had to be running the same video card BIOS on both cards. This isn't an issue nowadays, but I have no idea if this affects performance at all. This is something you could research on your own.

Well, thank you guys again and i am going to try and get that PSU darthbob was talking about.

if your going to go with SLI sont waste money on two 7900's just buy the 7950 GX2.

I'm pretty tired about hearing people hammer on about 'wait for DirectX 10!!'. It doesn't matter much, seeing as though Windows XP won't take advantage of Dx10, and (from what I've heard) most Dx10 games can revert to Dx9. Plus, you know how much a Dx10 video card might cost at launch?

I'm guessing quite a bit...

The bungie.net community is the halo PC community that is renowned for being unbelieveably sucky.

I'd say the power supply should be the only part of the computer that you shouldnt go cheap on. A bad PSU can cause some really annoying problems (freezing, booting issues, bsod's, and just about any problem you can think of). Having far drifitng voltages can be your computers worst nightmare, trust me I know from experience. Go for a trusted name like Antec.
