Looking at the following system (built from Cyberpower) to replace my fried Alienware (36mos old and died in a power surge), please comment:Key Components:CPU: i7 965 Extreme 3.2 GHz 8M L3 Cache LGA 1366 factory overclocked to 4.0GhzPowersupply: 2x 1000Watt units (Sigma Monster)MOBO: Asus P6T intel X58 chipset SLI/CrossfireX Mainboard triple channel DDR3/1600 SATA RAID w/eSATA GbLAN, USB 2.0 IEEE1394aMemory: 6GB DDR3/1800Mhz triple channel memory module (Corsair)Video: NVidia GeForce GTX285 2GB 16xPCIeHD: RAID-0 2x150GB Raptors 10000rpm SATA-II 3.0Gb/s 16MB Cache WD15000HLFSCooling: Asetek Liquid CPU extreme cooling system/extreme silent at 20dBA + 3 additional case cooling fansO/S:Windows Vista Home Premium w/service pack 1 (64-bit)My plan is to run FS9 and FSX--nothing else.Couple questions:2000watt power supply was originally intended for quad-SLI GTX295s, figure 1200watts should be plenty for above?What's the difference between Vista Ultimate 64-bit and Home Premium 64bit?ThanksR.Perry

Thats a nice system but not nearly needed to run FSX maxed out. If you truly just want to run FSX get a 920 I7 with the D0 stepping, x58 classified mobo and 1 GTX295 , ram don't matter to much long as its atleast 1600 - 6 gigs. You can overclock the 920 to 3.8 entirely on Air. FSX is extremely CPU dependant and does not take advantage of SLI or Crossfire. But hey if you got the money.

That system doesn't need more than a good quality 750W pwr supply...2KW is way beyond overkill.The RAID0 array doesn't do much for you except introduce complexity and cost...most of your HDD delay is due to head seek and rotational latency, not transfer rate, which is where RAID0 makes its mark. Personally, I'd go with a single 300GB Velociraptor instead. If you do go with a RAID, the quality of the RAID controller is important...most of the consumer-grade controllers, including (especially) those mounted on the mobo, aren't anything to write home about. And overclocking with a RAID controller as part of the equation can be a special brand of data-corrupting a** pain.If you've never used liquid cooling before, do some reading up on it and ask questions--what kind of warning system if the pump stops working, reliability (pumps are a notorious problem area), warranty, and maintenance requirements.Ask about the timings on the RAM they're using. All 1800MHz DIMMs are not created equal.I have Vista Ultimate--I know I have some access to system settings that Home version users don't, but I can't do a comparison. Ultimate will do disk encryption and backups too.On an OEM-built system I'd want to know more about the case--number and placement of fans, noise level, and access (side door, removeable panel etc etc).Good luckBob ScottColonel, USAF (ret)ATP IMEL Gulfstream II-III-IV-VColorado Springs, CO

I would say get a new D0 stepping i7 920 - most people are reporting 4.0Ghz+ with those babies...Hell my 920 C0/C1 stepper is running at 3.8Ghz no problem..Also the PSU you have specified is WAAAY overrated. I would say a quality 750W would be more than adequate! :(

yeah I too would change a few things:Asus revamped their P6T with the P6T v2, get that one instead:http://www.newegg.com/Product/Product.aspx...mp;Tpk=p6t%20v2A solid PSU, Corsair, PC Power and Cooling, Thermaltake:http://www.newegg.com/Product/Product.aspx...N82E16817703009Skip the liquid cooling, HSF's these days can do almost as good as liquid if not better, get this cooler:http://www.crazypc.com/products/ultra-120-1366-50985.htmlWith that HS youll be able to clock a 920 on D0 stepping to 4.0The GTX285 is what you want, the 295 is essentially two cards in one, and you only want one powerful cardhttp://www.newegg.com/Product/Product.aspx...N82E16814130442Also a single velociraptor will do the trick.

I agree with one of the replys that recommended EVGA X58 classified.
