Am thinking about adding another radeon 4890 for CF. Can my current PSU handel another 4890? and my motherboard has two pcie slots however it says that if i have crossfire each pci-e slot goes from x16 to x8? what will this mean in fps?
And will having 2 4890s be twice as powerful as a single 4890?
ok thanks and how will this xfire setup compare to a GTX295? taking into account the 7% you mentioned. Will the performance be about the same? And what kind of head room will there be when i have my 2 4890s?... would i be able to say add 2x 2tb hard drives in the future?
