I'm trying to push as much life out of my system as possible. I have a 7800gt and want to go sli. The problem is that I can't find another on ebay or the like with my serial, 256-P2-N519-AX. I see n517 and 18's, but no 19's. Could I buy one of these and run it with mine? I read in some other forum that with the newer drivers you can, they just both run at the lower clock speed. Any idea?

you can run any other 7800gt that has the same amount of ram. You dont have to have a specific model match. If one is faster then the other, they will both run at the lower speed. Check this one out, looking at your serial number I see that your card is EVGA-
Newegg.com - Recertified: EVGA 256-P2-N516-RX GeForce 7800GT 256MB 256-bit GDDR3 PCI Express x16 SLI Supported Video Card
That should work fine for what you are trying to do.

Are there any problems if you run two cards of different brands? I'm wanting to run an xfx 7800 gt that's the exact same amount of memory as my evga.

Thanks for the help, by the way.

No shouldnt be any problems....as long as they are the same memory size.
