Looking to build a PC. It will mostly be for gaming. My budget is 1,000 to 1,300 dollars. I am located in Ohio. I am willing to buy online. Will be using no parts from previous build. I don't need any peripherals. I haven't bought any parts yet. I have a rough build but its hastily put together. I can't post links due to restrictions. I do a lot of downloading and playing games that require a lot out of a computer. Mostly i could use advice on all components. 1. Tower. Something very spacious and open with room for plenty of cooling and upgrades. 2. Power Supply. Enough power to get me through another video card upgrade or two. 3. Motherboard/Processor. Quad or I7 preferably. (any thoughts on after market heat sinks/fan?) 4. Memory. A decent amount that is compatible with the MB etc. 5. Video card. ATI or Nvidia that can handle graphic intensive games. Thanks in advance for any suggestions and advice.
