7800gtx PERFORMANCE issues

[INM8]

Ok, well iv done a search on these forums, and theres a few posts about SLI'ing cards from two different manufacturers, but nothing about SLI'ing two different models. I have got a 7800gtx in my pc, and i also have a BFG 7800gt oc laying around from when i bought all my parts. I was going to sell it, but since im getting rubbish FPS in aoe3 with one card, i thought id try with SLI.

Will this work? Both have the same G70 core, so i dont see why it wouldnt. Will my 7800gtx be clocked down?

Dunno why im getting terrible performance in AOE3 anyway. Im really disappointed with this whole setup. At 1024 x 768, which AA on 2x and AF on 8x my fps sit around 45-50, and during a battle with artillery they drop down to 4-8 FPS which is rubbish. My 2405fpw should be arriving in the next few days, if this thing cant handle 1024 x 768, i dont know what its going to be doing with 1900 x 1200. Im running an X2 4400, 1gb Kingston hyperx, 2 x 250 samsung p120's in raid, a Gigabyte 7800gtx and the 81.95 forceware. Oh, and i have a 600w fortron PSU (Super Flower here in Australia) so it shouldnt be a power problem.

Not that I am aware of.

If you can, I will definately get a GTX to pair with my GT, but I am 99.9999999999999% sure you can't.

That would just be way to good to be true.

You "might" if you flash it with a 7800GT Bios and disable some pipes... but not very likely.

why not just sell the GTX and get a GT?

unfortunately, this isnt crossfire, where you can pair an X1800XT master card with an X1800XL...

SLI only lets you mix different vendors of the same card. example: asus 6800GT w/ msi 6800GT, xfx 6600GT w/ evga 6600GT.

you could also sell the GTX and get a GT like blackjesus said, but thats totally up to you.

..well i guess i could sell the GTX...but i hate selling things. Everytime i sell something, i almost get scammed, or i sell the thing to someone, who breaks the damm thing, then calls me and complains about it. When i refuse to refund their money, they decide their gonna call me up and harrass me about it every now and then. I hate that. Getting threats from people who seem pretty unsavoury.

I may try it anyway. I know theres like 0% chance of it working..but no-one seems to have tried it so i mayaswell.

Its probably a better idea to address my poor performance issues first, because something must not be right. The performance im gettig from my gtx seems more equivilant to a 6600gt.

It won't work buddy

I'd sell the GTX, but you could also sell the GT and spend a little more for another GTX

The crossfire mixing of cards is worthless because higherend card downclocks to match the lower end. I think XBITLABS did a review of a X1800XL and X1800XT and found the X1800XT losing enough performance to make card mixing not worth it.

Has anyone been having similar problems? I expected performance to better better with a gtx, but maybe this is normal. I dunno.

I seriously don't think it's normal, you might want to take a look at all your drivers.
