Saving money on a MB is penny-wise, pound foolish. The one component I refuse to compromise on is the motherboard. It's the heart of your system and its failure means starting over again. I've gone through several brands of MB in the last few years and while none are perfect, the most consistent have been the ASUS Extremes. My latest build is on a Rampage IV Extreme and so far, it's been an outstanding performer (7 months and running.) My previous build (now my back up/server, 3 years and counting) is centered on a Rampage III Extreme. If I needed to save money I'd shave it off other expenses like RAM and CPU.
The necessary disclaimer is that for my systems I don't shave the cost off any of the components, but if I had to, it wouldn't be the MB. RAM and CPU are great targets for saving cash since if you're not competing in speed competitions, you'll never get near the performance capacities of those components. Save the $200 somewhere else.
