Interesting... the Asus P5E-VM HDMI takes about a 5% performance hit due to 1024x768 IGP Windows desktop. With a video card, the performance is outstanding at stock and overclocked.
Sandra Bandwidth
We got a 2.7% performance hit on memory bandwidth due to the IGP, not as bad as I'd imagined. Good results at stock, outstanding when overclocked.
Sandra Latency
The Asus P5E-VM HDMI had mediocre latency numbers, but very good when oc'd.
