After doing the initial preview tests with 128MB Gainward FX5200 PCI video card here, it's time to swap out the 128GB Gainward FX5200 PCI video card for 2x 256MB BFG 7800GTX SLI video cards with modded bios at 473(525)/1350 clock speed and redo some tests


System:

• Intel Core 2 Duo E6600 QPGE B1 Step 5 ES
• Scythe Infinity + 2x Thermaltake 120x25mm 81cfm push-pull
• Intel D975XBX Bad Axe rev304 1334 bios
• 2x 256MB BFG 7800GTX SLI @473(525)/1350 84.56 drivers
• 2x1GB Gskill PC6400PHU2 HZ Micron D9GMH 0629 batch
• 2x 320GB Seagate 7200.10 SATAII hdds
• Pioneer DVD-RW Burner
• 1.44MB FDD
• 600W OCZ EvoStream modular power supply

I measured the system total power consumption using a Power-Mate power meter http://www.power-mate.com.au/. Ran 3dmark06 and PCmark05 and recorded the peak power draw values listed below.

@2400Mhz at 1.275v bios (1.259v)
Windows Idle watts = 187.7W
Windows Orthos Load watts = 231.9W
Windows TAT Load watts = 240.8W

PCmark05 = 359.8W peak

3dmark06 = 344.1W peak
Return to Proxycon = 337.9W
Firefly Forest = 344.1W
CPU1 - Red Valley = 253.5W
CPU2 - Red Valley = 266.3W
1 - Canyon Flight (SM 3.0) = 334.1W
2 - Deep Freeze (SM 3.0) = 335.7W



@3600Mhz at 1.425v bios (1.394v)
Windows Idle watts = 218.9W
Windows Orthos Load watts = 303.7W
Windows TAT Load watts = 324.4W

PCmark05 = 401.3W peak

3dmark06 = 394.8W peak
Return to Proxycon = 386.5W
Firefly Forest = 394.8W
CPU1 - Red Valley = 290.6W
CPU2 - Red Valley = 289.6W
1 - Canyon Flight (SM 3.0) = 384.9W
2 - Deep Freeze (SM 3.0) = 384.9W

For the stressprime 'Orthos' and TAT load tests there wouldn't be as much a power draw difference between 7800GTX SLI vs FX5200 PCI since there isn't any video card load in those tests. You can see the difference in power draw when video card load comes into play with 7800GTX SLI configuration.

Now to compare all the data including FX5200 PCI test in a nice graph
