I'm building another PC, mainly for charting and news - but also to run TWS as a backup broker. Here's what I'm currently planning to buy: ------------------ ANTEC NSK4000 Mini Tower Case, 1x120mm fan ASUS Maximus Formula, X38, Socket-775, DDR2, ATX, 2xGbLAN, Firew, 2xPCI-Ex(2.0)x16 INTEL Core 2 Duo E8400 3.0GHz FSB1333 6Mb ZALMAN CNPS9500AT Ultra Quiet CPU Cooler 2 CRUCIAL DDR2 BallistiX PC8500 2048MB CL5,Kit w/2 BallistiX 128Megx64 (total of 4 GB) 2 PNY Quadro NVS 440, 256MB DDR, PCI-Express 1x WESTERN DIGITAL Digital Caviar GP 1TB SATA2 16MB 7200RPM Seasonic M12 600W, 120mm fan, 2xPCI-E NOCTUA NF-S12-800, 120mm fan, 800RPM, 8 dB(A) NEXUS Nexus 80mm Real Silent Vifte, Sort, 17,6 dB(A), 20,2 CFM, 1500 RPM ------------ I want it to be powerful yet quiet. Will be running six screens. XP Pro. TWS, Investor /RT, QuoteCenter and another app for DJ news. Not used for main trading. I might overclock memory and the cpu, but I don't think I'll be needing it tbh. Replacing the Antec fan. - Comments on the RAM? - Motherboard too much or appropriate? - I don't quite see the point of the PCIe 16x vs the 1x version of the graphics cards. Am I right about this? - The Antec tower, any comments on that? I don't want to go bigger, although that would be favourable for temperature etc. I only build a pc or two every other year or so, so each time there's a whole new set of hardware to learn about and new techs to check out.
