The P55 Extreme4 is a nice board. It combines some great technologies into one package. You have everything from PATA/Floppy to four port RAID for SATA 3.0. The option for a second pair of USB 3.0 ports is also a handy little feature.
While all of this is great, there were a few items that just did not sit well. The advertised software bundle was a little disappointing as much of it was only trial software. We also would have liked to have seen much better HDD and gaming performance. Still, the P55 Extreme4 is suited to both the consumer desktop market and could even fit into the workstation market. The four SATA 3.0 ports could be a great setup for A/V work or even as an output for 3D projects.
Plus, with its $149.99 price tag at NewEgg.com, it would be a steal for the gamer or prosumers looking for the most bag for their buck.
