okay i know the pcie 8x doesnt cause that big a performance loss compared with 16x since the card doesnt even use that much bandwidth.
However My mobo only has 4x pci-e. Sooooo say i get a new dx10 card in a few months, what sorta performance loss would i see???
edit: Oh by the way, the rest of my system is: E6600, 2 gigs of ram, 250 gb HDD, 400 watt psu (for the moment, will upgrade if i get a new card)
IIRC crossfire on my board suffers a small loss in performance because of the 2nd slower PCI-E slot. SLI with hacked drivers suffered a big performance hit when compared to a SLI mobo with 2 PCI-E x16 slots.
