I am looking to build a new PC. This would be my first time. I have a million questions, I don't know much about this. I've looked into buying pre-assembled pcs but it doesn't seem worth it. The other thing is the sites I was considering apparently are a terrible headache to deal with if they ship you a pc with malfunctioning hardware. Thus I would like to build my own. What are you going to use the PC for? Gaming. Software Development. Specifically Dota 2 and the upcoming Diablo 3. How much is your budget? $800-$1300. This is a big range. I don't need top of the line products. I want something that has a good performance/price ratio and that will be able to run games well for the next 3-5 years. Where are you located? (a.k.a. fill out your profile) Canada Are you willing to buy online? Yes Are you going to re-use any parts from an earlier build? Yes. Here is what I currently have that I would consider reusing: GPU : NVidia GeForce 7600 256 MB Mem(if I must but I would much rather upgrade, meets Dota 2 recommended GPU spec. Would like an HD card) HDD: samsung sp2504c 250GB 300MB/s transfer speed 7200RPM. Apparently HDDs are expensive right now because of messed up production. I really don't mind re-using this. I know that Main Memory accesses are very slow and if I was to purchase a HDD it would have 1TB store space and ~600MB/s transfer speed. Will this difference affect the performance much? Is main memory accessed that often while gaming or is everything stored in ram? 300 Watt PSU I don't know if any of this stuff is reusable so I will paste a few of my current system specs: Motherboard Name Asus A8N-E (3 PCI, 2 PCI-E x1, 1 PCI-E x4, 1 PCI-E x16, 4 DDR DIMM, Audio, Gigabit LAN) Motherboard Chipset nVIDIA nForce4 Ultra, AMD Hammer System Memory 2048 MB (DDR SDRAM) BIOS Type Award (11/25/05) Communication Port Communications Port (COM1) Communication Port ECP Printer Port (LPT1) Do you need other peripherals like a monitor, keyboard and mouse, among others? I'm hoping to purchase a big monitor. I currently have a 19-inch monitor that I bought 4 years ago that works very well. Wondering what gamers out there's thoughts are on bigger monitors. Another monitor would also be nice for programming. I would also like a decent headset with mic. Not picky with this one, but I would prefer it not smother my ears (does not have to be noise cancelling). The cheapest speakers possible that are still acceptable for movies. Have you already bought any parts? No. Do you have an Operating System (OS)? Yes. Windows 7, 64 and 32 bit, and Windows XP. Would like to run the better option of windows 7. Will you need any aftermarket cooling, such as a CPU\GPU cooler or a watercooling setup? Not sure. Depends on the above! I would like to stay away from overclocking if possible since I don't really know how it's done and if it's a good idea if I use my PC for prolonged periods of time at once. Other things I would like to mention: Here is the processor I was hoping to get : Processor: Intel Core i7-2600 Sandy Bridge 3.4GHz (3.8GHz Turbo Boost) LGA 1155 95W Quad-Core Desktop Processor Intel HD Graphics 2000 BX80623I72600 Is this processor still too new this having a bad performance increase/cost increase ratio from say one of the i5s? Since I would like the PC to be upgradable, is this a good way to go? I was looking at the TechSpot Enthusiasts PC recommendation. They recommend a $150 case. Is this really necessary? I don't care at all if it looks nice, I just want the cheapest possible case that has proper cooling and can fit all my hardware. The other thing is the sound card. From my experience, the onboard motherboard soundcard is usually sufficient. Thoughts? When buying a pre-assembled PC, it usually comes with a 1+ year warranty. How are warranties when you buy all the hardware separately? How do you tell if the components you want are compatible with one-another? Thanks so much, I really appreciate any responses and that you took the time to read this.
