It is funny that the only people that say that you will not be able to put a 7800 in a 9300 are the XPS2 owners. You guyz are sooooo saaaad.

I think i will side with the 9300 owners on this one. Someone has already succeeded in making a 6800 ultra work in a 9300 (without changing motherboard and with the same performance as XPS2) and that's more difficult than making a 7800 work in a 9300. The only problem is that you may not be able to buy it from spare parts and may need to prove you've got an XPS2 before you buy i

It's the same mobo.
only 7800 GT and 7800 GTX exist, there is no ultra, it was cancelled.
