I have an ASrock 939 Duel SATA2 so i can have agp and pcie. I just got an EVGA 7800GT to replace my 9800pro. Is it (in theory) possible to sli them both? I doubt you can...

you cant SLI Nv and ATI no, but you can run them seperately together. though im not sure your motherboard will support the use of AGP and PCI-E at the same time, i would of thought it would be PCI-E OR AGP

but anyway http://www.hexus.net/content/item.php?item=4151 read that.....its completely possible and actually very easy to run ATI and Nvidia cards together in the same system. not in SLI, but seperately allowing for 4 monitors.

he combined a 7800GTX and a X1800XL together....and they played nice.

In theory it's possible, but not using the methods nvidia and ATI have invented in sli and crossfire. Megabyte, who was bought by alienware, had a method to sli any video card, but it only worked well when the two cards were of approximately the same power and even then wasn't great. (the two cards output different image quality, support different features and code paths so the games had to use the lowest common denominator, and could end up rendering at different framerates and a blurry line was placed in between the two halves of the image to try and hide where the two seperate images intersect)

Anyhow, the 7800GT is probably at least 4x the speed of the 9800 pro, there wouldn't be much benefit to using the 9800pro and you'd lose all the nifty SM3.0 features.
