I've used both these boards. I'm afriad I'm not able to report on overclockability as I don't often indulge in the art.
However, what I can say is that the Striker has a couple of small but significant issues that are as yet unresolved and required many hours of tinkering in order to achieve what I remain uncertain is an entirely stable setup. Additionally, it would seem that recent Nvidia boards (590, 650 and 680) are extremely fussy over memory, even Asus's own QVL list - which is an utter joke besides - cannot be relied upon
By contrast, the Bad Axe 2's only hiccup was a bizarre reluctance to boot from my CD-ROM drive, despite my setting the boot priority correctly, I eventually managed it by leaving a floppy disk in drive A
go figure.
Anyhow, since windows has been safely installed , it has never even looked like crashing - 20 hours prime/orthos stable running with 4gb g.skill
memory set to 3-4-3-8. I would also trust the Intel's ICH7 SATA controller far more than Nvidia's effort, which has lately been the subject of numerous complaints, though admitidly, these are now being addressed.
