quick SLI question

[oguessous]

I have an EVGA 7800 GT. If I choose to go SLI, do i necessarily need the same brand? Or would any other 7800 GT do just fine?
Also, how much of a performance boost does SLI give?

Thanks ...

Any 7800GT will work, regardless of brand, but it must be the same memory config. Also, if one card is clocked higher than the other, both cards will default to the clock speed of the slower card.


Performance gains will depend on the game, your system, and resolution, etc.. I noticed a nice gain in Source engine games with all details maxed out. I'm extremely pleased. I only run at 1280x1024, but I max out the AA and AS, etc. Man, it's sweet!

Actually, that isn't true, you can have different memory sizes and clock speeds and both cards will maintain their default clock speed, no downclocking occurs.

Depends on the forceware being used

Im wondering about that too. I have 2 7800gts with one clocked at 445 mhz and one at 470 mhz. Coolbits shows me my clockspeed at 470. Does that mean my other one is running at 470 also? Does it matter which PCI/E slot they are in?

If your using hte most recent ForceWare Drivers then any GT card will work. No down clocking will occur. I'd put the faster card in the 1st slot though. I'm not sure that matters much but that's what I'd do. Makes the most sense to me.
