There's nothing to not like about the 8350. Power consumption is around 10% less compared to the 1100t (3.3Ghz) and to top it off, it has two extra cores. Compared to my X6 @ 3.9Ghz, WUs take slightly longer on the 8350 to complete (about 15-20 min more) but since you're doing 8 at a time the FX has the upper hand. The downside is that, based on some reviews I've seen, power consumption grows exponentially with overclocking. A 10% OC would increase power consumption by 20%, at 5Ghz (25% OC) you'd be looking at a 70% increase (see FX-9590). Running them stock is the sensible approach if you plan on crunching 24/7.
