PiFast
A good indicator of CPU/Motherboard performance is version 4.2, by Xavier Gourdon. We used a computation of 10000000 digits of Pi, Chudnovsky method, 1024 K FFT, and no disk memory. Note that lower scores are better, and times are in seconds.

Lower is better
The K8T Neo manages to beat the K8V Deluxe by a mere .06 seconds, so they are pretty much dead even. If crunching numbers is your game, the K8V won't let you down.
VirtualDub Audio Extraction
We ripped the audio of at 44 100Hz, no compression using VirtualDub 1.5.8 (Build 18068). Times are in seconds, and lower is better.

Lower times are better
No change between the two boards, as they both use the same CPU, and motherboard chipset.
TMPGEnc 2.521
We used the same Animatrix file and the WAV created from VirtualDub, and converted it into a VCD compliant MPEG-1 file. Times are in minutes:seconds, and lower is better.

Lower times are better
Very close again, but the K8V takes another victory here, even though it's a narrow one at three seconds.

A bit of a surprise here as the K8V lags behind the K8T in both gaming benchmarks. For kicks, I fired up Quake 3 as well, and the K8T took that one also. The differences in gaming performance is minor though, and the K8V is still plenty fast.
