I hope. My understanding is they just need the same GPU.
Yes. I'm

at all the people asking that question on AT of all places. Same GPU, SLI works. Thing with the 8800GTS is that some of them are based off different cores.
copypasta from Wikipedia
The first releases of the 8800 GTS line, in November 2006, came in 640 MB and 320 MB configurations of GDDR3 RAM and utilized NVIDIA's G80 GPU.[16] While the 8800 GTX has 128 stream processors and a 384-bit memory bus, these versions of 8800 GTS feature 96 stream processors and a 320-bit bus. With respect to features, however, they are identical because they use the same GPU. [17]
Around the same release date as the 8800 GT, NVIDIA released a new 640 MB of the 8800 GTS. While still based on the 90nm G80 core, this version has 7 out of the 8 clusters of 16 stream processors enabled (as opposed to 6 out 8 on the older GTSs), giving it a total of 112 stream processors instead of 96. Most other aspects of the card remain unchanged. However, because the only 2 add-in partners who are making this card (BFG and EVGA) have decided to overclock it, this version of the 8800 GTS actually runs slightly faster than a stock GTX in most scenarios, especially at higher resolutions, due to the increased clock speeds.[18]
NVIDIA released a new 8800GTS 512MB based on the 65 nm G92 GPU on December 10, 2007.[19] This 8800GTS has 128 stream processors, compared to the 96 processors of the original GTS models. It is equipped with 512 MB GDDR3 on a 256-bit bus. Combined with a 650 MHz core clock and architectural enhancements, this gives the card raw GPU performance exceeding that of 8800 GTX, but it is constrained by the narrower 256-bit memory bus. Its performance can match the 8800 GTX in some situations, and it outperforms the older GTS cards in all situations.[19]
I don't know if they'll SLI if they're different.
