Depends a lot on which graphics card you want to use.
Here's a quick test I just did on my ASUS A8V-E Deluxe, with setting the CPU frequency scaling support in Linux to "powersave" and "performance" (all tests done with the proprietary BIOS):
No graphics card, performance: 61.6 W No graphics card, powersave: 55.2 W
Old PCI VGA graphics card, performance: 64.8 W Old PCI VGA graphics card, powersave: 58.6 W
Cheapo PCI-E graphics card, performance: 74.3 W Cheapo PCI-E graphics card, powersave: 67.8 W
Here's the lspci for the cards:
00:0c.0 VGA compatible controller: ATI Technologies Inc 3D Rage Pro 215GP (rev 5c)
02:00.0 VGA compatible controller: ATI Technologies Inc RV370 5B60 [Radeon X300 (PCIE)] 02:00.1 Display controller: ATI Technologies Inc RV370 [Radeon X300SE]
There are certainly a lot more power-consuming graphics adapters out there, this is the cheapest PCI-E one I could get (I couldn't care less about 3D performance).
HTH, Uwe.
