Here's the announcement on ASUS News site.
Microsite here with comparisons.
ASUS got 6 of them:
- the F1A75-V EVO seems to be the high-end one.
- the F1A75 doesnt have video-output so you'll need a dedicated card for this.
Wonder what will cost these, strangely the 990fx boards doesnt effected much the 890fx boards' price.
