Advice and comment sought on a new build (SSD, SATA 6 GB/s,

I'm getting close to a final decision on my next PC. Hopefully able to run FSX in a decent way ...To be used surely for FSX (and perhaps FS9) but also as my main "production" machine. That is Office and web applications, as well as playing other games : i.e Silent Hunter 5, Napoleon Total War etcI plan to order from a UK system builder - as no local (that is Danish) builder seems to to have what I would like to order.I'm well aware that building your own might save me quite a bit, but while money certainly still is a consideration, time is also money and for now time is a bit more scarce than money ...Proposed System Specification:- Case: Antec 902 Nine Hundred Two Ultimate Gaming Case - Black- Power Supply: Corsair TX 650W ATX SLi Compliant Power Supply- CPU: Intel Core i7 930 2.80GHz Overclocked to 4.00GHz- Motherboard: Gigabyte EX58A-UD3R Intel X58 (Socket 1366) PCI-Express DDR3 Motherboard (Supports USB 3.0 and SATA 6Gb/s)- Cooler: Prolimatech Megahalems Rev B CPU Cooler with Akasa Apache Black 120mm or Corsair H50-1 High-Performance CPU Watercooler- RAM: Kingston HyperX 6GB (3x2GB) DDR3-12800CL9 (1600MHz) Tri-Channel- Hard Drives: Corsair Nova 64GB 2.5" SATA-II Solid State Hard Drive + 2 x Western Digital Caviar Black 1TB SATA 6Gb/s 64MB Cache- Graphics Card: Radeon 5850 or Nvidia 470 (if available)- Sound: Realtek ALC889 7.1 Channel Sound (On-Board)- Optical Drive: LG DVD+/-RW SATA Drive- Edimax EW-7727In nMax 300Mbps Wireless Desktop PCI Network Adapter- OS: Dual boot: Win XP Pro and Win 7 (Home Premium or Ultimate)So a couple of questions:- What is your experience (if any) with Overclockers.uk?- Any obvious bottlenecks in the specs?- Advice on choice of CPU cooler?- Would there be any noticeable improvement in getting RAM wiith a lower latency - at a very considerable price?- What is your experience (if any) with Corsair Nova 64GB 2.5" SATA-II Solid State Hard Drive and Western Digital Caviar Black 1TB SATA 6Gb/s 64MB Hard Drives?- Choice of GFX - not to start a war af religion, rather to hear the voice of those with first hand experience.- I plan to install the OS('s) to the SSD, FSX to one of the "Blacks", other programs and games to the other "Black" - if I finally decide to install FS9 should it go to the FSX HD or the the "other programs" HD?- Shoul I install FSX (and possibly FS9 ) under XP or Win7?/Lars
