Well two 8800's could be any 8800 right? I'll take two 8800GTX's please
If there is no money involved I'd take that 9800X2 which performs fine enough and then a normal Intel chipset board (X38/X48_Well two 8800's could be any 8800 right? I'll take two 8800GTX's please)
One GX2 is better than two 8800GTS 512mb's. Even though the GX2 has two of the G92 cores that the 8800 has, it has a better SLI rate. I believe it's 2x just like the 9800GTX. So basically the GX2 is like 100% SLI of two 8800's.
