The Athlon 64 FX 60 from Advanced Micro Devices is an excellent processor for gaming, and it offers strong competition for Intel in regard to productivity. The processor is the power behind the Nemesis Custom Gaming PC from Monarch Computer Systems. It clocks at 2.6 GHz, somewhat lower than AMD's previous 2.8-GHz FX57, but the reduction is not noticeable during real-world gaming. The FX60 is combined with 2 GB of dual-channel Double Data Rate SDRAM, which improves throughput. Since data-handling performance is critical, the Monarch has a 74-GB Western Digital Raptor hard disk to handle system tasks and two 400-GB Western Digital Caviar SD drives in a RAID 0 configuration to handle data tasks. Additionally, the Nemesis comes with two Plextor PX-716AL DVD burners and a Creative Labs' X-Fi Platinum sound card. There is a front-drive panel so connecting accessories is easy. The Thermaltake Shark tower enclosure holds the components, and the tower, Logitech LX 700 wireless keyboard, and mouse have a Fine Pearl paint job. The Nemesis uses a pair of eVGA GeForce 7800 GTX KO SLI graphics cards that each carry 256 MB of DDRe configured in a Scalable Link interface. This configuration provides graphic frames at a faster rate than users will need. Testers using the COSBI OpenSourceMark benchmarking tool found the Nemesis to be faster than an Intel Pentium 640 that was overclocked to 3.55 GHz, as well as a dual-core 3.2-GHz Pentium D 840 Extreme-based computer. While one video test showed excellent results, the Nemesis was slow in a video test that increased stress on the entire system. However, unlike many gaming computers, the Nemesis handles productivity well, and it is excellent for use by serious gamers.
