Okay, well It looks like I'll be adding 2 more HD4890-OC cards to my I7 next week, so now I have a question in general about bandwidth.
My I7 motherboard (Asus P6T, original, no WS no revoultion), runs the 3rd PCI-Express 16x slot at 4x if both of the other two slots run at 16x16x, so.. two questions arise from this.
1.) Does the ATI/AMD CrossFireX Bridge Connector provide additional communication bandwidth to the overall CrossFireX setup, enough to give performance above the 4x PCI-Express slot?
2.) Will I see a performance increase adding a 3rd card at 4x (even with the CrossFireX Bridge Connector) to my other two HD4890-OC cards in the first two 16x slots @ 16x speed (both of em)???
