Video card SLI question

WhiteW0lf · 12-05-06, 12:52 AM

Ok I currently have a 7800gt PCI-E and was thinking of getting a second and running them as SLI, I do have dual PCI-E slots, with my system config below in my sig will this significantly increase my visual performance/framerates on all games and do I need to buy anything else to run in SLI? I noticed in pictures there is a special piece to clip over the cards to connect them.

Thanks for the help fellas.

That special piece should have come with your motherboard. Also, you're going to get a max performance boost of something like 25%, and that only with games that specifically support SLI, which I don't think SH3 does. The second card will also have to be a 7800gt, but I think the manufacturer doesn't matter so much.

Thanks guys but being the impulsive guy I am I just ordered a Geforce 8800GTS 640MB from NewEgg for $462, this will blow all games away. The only thing is my wife will kill me if I let her find out, I guess thats why we have seperate credit cards

I hope you have at least 500W PSU.

I recently bought a new system and I had the dual sli cards put in ...I played Doom 3 and the Resurection of Evil on it's highest video settings and it played flawlessley...sorry to have beaten them both now....I was gonna get that microsoft 10 flight sim maybe or oblivion and try them out...but in all games now they play great..1800$ well spent.

Can I double up my 6800 ? [somehow I don't think Santa's coming down the chimney with a shiny new do-it-all Computer !]:rotfl:

To run SLI all you need is two video cards with the same core (G71 for the 7900GT/GTX, G70 for the 7800GT/GTX/GTX 512) and a PSU capable of powering both. You can have different amounts of memory even.

That 8800 will destroy even 7800GT SLI if I'm correct.

It is also VERY important to ensure your motherboard supports SLI.

Most people (excluding BIOS hackers) won't try to run SLI on a non-SLI mobo.

That is correct some people online had dual 7950's and bought the 8800 and they said it blew away any dual SLI cards out there. My order shipped yesterday I cannot wait to get this damn card in, I have oblivion but dont play it but I will check that game out to see the difference.
