My friend John has two systems: 4890 CF and 460 SLI. I also have two systems: 8800GT SLI
(2 different brands) and 460 SLI. John's GTX 460s are Palit Sonic Platinums (800MHz core).
My GTX 460s are EVGA FTWs (850MHz core), though I also have a Platinum which I'll be
testing in a P55/i5 760 system later. NB: All GPU clocks are given as 'Core/Shader/RAM'.
Note that my system with the 8800GTs used to be an i7 860, but now it's an i7 870 with
a higher clock.

Key:

  8800GT/G = Gigbyte 8800GT 512MB Zalman (Turboforce Edition), stock @ 700/1700/1900.
             oc'd to 775/1850/1900 on my i7 860.

  8800GT/A = ASUS 8800GT 512MB Glaciator, stock @ 602/1512/1800, oc'd to 685/1725/1900
             on my i7s, oc'd to 650/1608/1900 on the Athlon64 X2 6000+ 3.225GHz PC
             which has an ASUS M2N32 WS Pro mbd and 4GB DDR2/800 RAM.

Data is grouped according to CPU/system (groups with the highest
multi-CPU render score listed first), and subgrouped by graphics card
model in order of X-CPU score. This is to make it easier to compare
different configurations, eg. when checking for bottlenecks. The group
containing the highest overall multithreaded CPU score is listed first
in each table.
