Single HD 4870 X2 vs Two HD 4870s on P45

By: Shawn Baker | AMD CrossFire Articles in Video Cards | Posted: Aug 14, 2008 4:00 am

Smooth Creations Test System Setup


Processor(s): Intel Core 2 Extreme QX9650 @ 3.9GHz


Motherboard(s): Foxconn P45-A


Memory: 2 X 4GB G.Skill MQ 6-6-6-18


Hard Disk(s): Western Digital Raptor 150GB


Operating System: Windows Vista SP1


Drivers: Catalyst 8.7 & R700 Only Driver


We couldn't let that beast of a Smooth Creations system rest for too long, so we've placed the power cord back in, hooked up our keyboard, mouse and 30" monitor and cranked the CPU up to 3.9GHz.


What we've done is run through our Vista benchmarks to see how we go with the two setups. Let's find out how we go and if my thought process was correct in wrapping up the HD 4870 X2 the other day.




Version and / or Patch Used: Build 110
