After vetting a series of different components, have finally landed on a winning combination. Strongly recommended for those "Do it Yourself" types seeking rock solid stability and power. Hope the component list below will help generate ideas where to start looking. High performance/cost ratio: ~$950 plus cost of LCD's. I'm rather anal, vetted components for a great deal of time, been building my own systems since the late 90's. Extensively stress tested(Prime95,Memtest,etc) and is bulletproof at 3.2GHz (I throttle it back to 3.0 for trading, however). Use caution when looking at current Asus motherboards. For years I have been an Asus die-hard given their inherent stability, but the last year has shown a significant decline in quality. I am not alone with this sentiment. Abit/Gigabyte have come out with real winners for P35 chipset. X38 chipset still too immature for my taste. 03/2008 Trading System Build Processor: Intel Quad Core Q6600 G0 SLACR @ 3.2GHz OverClock ($199) www.microcenter.com Motherboard: ABIT IP35 PRO ($135) http://www.newegg.com/product/produ...N82E16813127030 Memory: 2 x 1GB G.SKILL DDR2 800 (PC2 6400) Dual ($45) http://www.newegg.com/product/produ...N82E16820231098 CPU Cooler: Tuniq Tower 120 ($40) http://www.newegg.com/product/produ...N82E16835154001 Video Cards: 2 x eVGA 8600 GT PCI-e x16 (2 x $60) http://www.newegg.com/product/produ...N82E16814130085 Hard Drive: WD Raptor 150GB WD1500ADFD 10,000rpm 16mb SATA ($159) www.microcenter.com 20x DVD Samsung SATA Burner ($30) http://www.newegg.com/product/produ...N82E16827151154 Antec P182/P180 Case ($100) http://www.newegg.com/Product/Produ...N82E16811129025 Power Supply: Corsair HX620 ($115) http://www.buy.com/prod/corsair-620.../203270718.html Made by Seasonic. Very high quality, server-grade components. XP Pro SP2 ($0) System powers (3) 24" Samsung LCD's. System is virtually dead silent. Reviews on Newegg associated with each component speak for themselves. Extremely satisfied. Smoothly runs more charts in Multicharts than I know what to do with. CPU load is roughly 1/7th compared to my retired AMD 64 3000+ running same trading platform.
