I want to start by saying that I am new here and I am fairly new to building computers. I know that, with me being a novice, I am setting my sights high by choosing to plan a modern gaming rig and that it is a little presumptuous. And on one final note I have nowhere near the means to build a modern gaming rig or buy one. I am just doing this for fun, learning, and perhaps as a business venture. I can definitely see myself manufacturing and selling custom computers. Enough of all that. Thinking about what computer I would like to have, I decided to head over to Newegg and see what I could come up with. My goals were to select components for a modern gaming rig that could run all current and past games at full quality and most future games (within the next 5 years) at full or functional quality. Despite being a newbie, I am aware of the competition between AMD and Intel. I decided to go against looking into quad cores even though they are the technology of the future because I am building a modern rig, not ultra-modern. This may be unfounded, but I also believe brand new hardwares are unstable? And when comparing dual core processors, it is generally agreed that AMD is better for gaming. I selected the AMD Athlon 64 X2 6400+ Windsor 3.2GHz 2 x 1MB L2 Cache Socket AM2 Processor. It appears to meet my performance requirements and the price looks very appealing. Moving on to the graphics card, I selected the GeForce 8800GTX 768MB 384-bit GDDR3 PCI Express x16 HDCP Ready SLI Supported Video Card. It is a great card and I like the Vista and DirectX 10 support. On a side note, what would the differences be between having one versus having two? Really what I'm asking is can one handle the latest games on max quality with Windows Vista Aero running as the OS. The prices hurt compared to other things, but it is a top of the line item and if I get the chance to build this soon, I want to know. Some difficult and confusion arose during the selection of a mobo. I chose the ASUS CROSSHAIR AM2 NVIDIA nForce 590 SLI MCP ATX AMD Motherboard because it appears to be compatible with the above CPU and GPX. If it is not PLEASE correct me! Assuming that they are compatible I moved on to selecting memory and chose 4 sticks of GeIL Value Series 2GB 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Desktop Memory to gain max RAM on the computer. My primary concern is that it is a company I've never heard of. Are the products reliable? There were no reviews. I want the best sound for the buck so I decided I am going to replace the mobo onboard audio with a Creative SB X-Fi Xtreme Audio 7.1 Channels PCI Express Interface Sound Card. I've heard it is the best for gamers. My concerns are: Will it use the PCI Express x4 slot if I have both x16s holding graphics cards? Is it a reliable product? I've heard a few complaints. Not enough to turn me off, but enough to make me cautious. The hard drive I selected is the Western Digital Caviar RE WD1600YS 160GB 7200 RPM 16MB Cache SATA 3.0Gb/s Hard Drive. I can purchase an external hard drive if I need to store things in an archive. All the games which I would purchase will fit in 160GB. I don't need anymore size. Is it the best type for my mobo? I'm sure it works, but are access times the best? I am running short of time while writing this so here are two more things to consider. The optical media drive is the ASUS Black 18X DVD+R 8X DVD+RW 8X DVD+R DL 18X DVD-R 6X DVD-RW 14X DVD-RAM 16X DVD-ROM 48X CD-R 32X CD-RW 48X CD-ROM 2MB Cache SATA DVD Burner with LightScribe, the NIC is the Intel 10/ 100/ 1000Mbps PCI PRO/1000 GT Desktop Adapter 1 x RJ45, and the power supply I selected is the PC Power & Cooling Turbo-Cool 1KW-SR EPS12V 1000W Continuous @ 50°C Power Supply 100 - 240 V UL, cUL, CE, TUV, RoHS. I had the most trouble with that and I'm not sure if it is sufficient or reliable. I know this is a lot to ask. I would like you to analyze this to make sure everthing is compatible and reliable, with special consideration for overclocking. I am confident I can safely overclock. I just want to know if there will be any problems with the selected hardware and what the limits will be. Also, I know internal temperatures will be high. I am certain I will need water cooling. Are additional fans necessary? I would appreciate recommendations for cooling systems. I need to select a case. I want to be able to view the interior of the computer and have cool lighting with everything fitting inside, so appropriate size. Any suggestions? On a final note I would like to know where I can get these cheapest at. I am sure Newegg is one of the best, but almost all of these parts had no rebates or OEMs. Can I get deals if I have a small business manufacturing and selling computers? I would also appreciate it if you reviewed these parts for effectiveness. If you know something better please tell me. I will have a new post for external hardware and peripherals. I am sorry for asking for everything but the kitchen sink, but I'm inexperienced. Please take a little time to help out a noob and don't be frustrated. I've come a long way and I'm sure I can go a lot further with your help. Thank you!
