Let me get this straight. I wanted to build a rig that would maximize the performance potential of a triple crossfire Radeon 4850s with 512 megs of RAM. So I thought these components would be a sensible choice that would leave nothing back as far as performance potential in a happy median between raw CPU power and GPU power and not need a nuclear power center to stay stable. I'm salvaging some parts from an AMD Spider based rig to complete the project. Operating System: Windows Vista Home Premium 64 bit OEM http://www.newegg.com/Product/Product.aspx?Item=N82E16832116488 Motherboard: Gigabyte GA-EX58-DS4 http://www.newegg.com/Product/Product.aspx?Item=N82E16813128366 What more could you want? Up to 24 gigs of crazy DDR3 RAM and 6 friggin memory slots!!! Well one more PCI express slot maybe for quad crossfire but that is not worth the extra $100that cost with the X58 boards and if you switch to SLI you won't need that 4th slot. Processor: Core I7 920 2.66ghz An absolute great performer!!!! Better than even the fastest Core 2 Quad!!!! http://www.newegg.com/Product/Product.aspx?Item=N82E16832116488 A great article on performance of I7 with multi GPUs. http://www.guru3d.com/article/core-i7-multigpu-sli-crossfire-game-performance-review/ The gap between I7 and anything else is substantial. System Memory: 12 gigs of Crucial DDR3 1066 Triple Channel Memory. You can never have two much as far as I'm concerned. http://www.newegg.com/Product/Product.aspx?Item=N82E16820148246 Video Cards: 3 Visionek Radeon 4850s in triple crossfire I bought a while back Monitor: HP LP3065 30" IPS Monitor 2560 * 1600 resolution Yes I will have to limit FSAA due to a 512 meg frame buffer limitation but at 4 million pixels FSAA above 4X is really overkill and even off looks just fine. Sound Card: Soundblaster X-Fi Extreme Gamer Hard Drives: 2 Western Digital 500 Gig Sata 2 drives in Raid 0. http://www.newegg.com/Product/Product.aspx?Item=N82E16822136178 Case: Antec 300: Why go with anything else? Well, the 900 has the front fans already installed so maybe you might want that one. Power Supply: XCLIO 1000 watt power supply with 2 35 amp 12v rails I don't have the system together yet. I will get the parts to complete the build early next week. I've been an AMD supporter and builder for so long and the performance with I7 was just too much to resist. And with rumors of a Deneb delay it seemed like the right thing to do. What do you guys think?
