So there has been a lot of people asking about how much CF (Cross-Fire) on a pair of high end HD 4870's will be impacted by dual x4 , dual x 8 and dual x 16 PCI-e lanes.
I will be starting to test just that late this week so we can see just how much the various chipsets and lanes impact and potentially bottleneck 4870 CF.
System Spec:
CPU : Q9650 (450 x 9)
RAM : Crucial Ballistix D9 DDR2-1066, OCZ Platinum DDR3-1600
GPU's : 2 x Visiontek HD4870
Motherboards:
GA-X48T-DQ6 - Intel X48 Chipset - Dual x 16 PCIe 2.0 slots
ASUS Maximus II Formula - Intel P45 Chipset - dual x 8 PCIe 2.0 slots
GIGABYTE GA-EP35-DS3P - Intel P35 Chipset - Dual x 4 PCIe slots
CPU will be a 45nm quad.
I will only run at 1680x1050 and 1920x1200 res and a couple of synthetic benchmarks and a few gaming benchmark, not too many as it takes too long to report on the results.
