What do you pick - E21xx OR E7200 OR Others, and what RAM? I'm a budget overclocker. I'm also a price/performance geek. My current pick is E21xx which is very cheap and can overclock to 3.0Ghz easily with stock cooler. I'm also interested in the new E7200 but it's 100% expensive at my local stores (I don't buy online!). My choice of the coming motherboard is Foxconn P35A-S. 1. What's the difference between E21xx and E7200? As far as I know, the only differences are cache size and clock multiplier. Anything else? 2. Normally speaking, how far can E7200 go on stock cooling? How good is the overclockabilty of E7200? I plan to use its stock cooler only. I don't plan to spend extra bucks on aftermarket coolers unless it's proved to be worth it, price/performance-wise. 3. How much RAM should I get? My choices: 3GB: 1GB + 1GB + 1GB 3GB: 2GB + 1GB 4GB: 2GB + 2GB Does it hurt if I mix different RAM brand, or different size/timings of RAM? I'm using Windows XP Pro. I need to receive a lot of streaming data (10+). I may do occasional video & audio editing/recording. I don't often play games. DDR2 should be obsolete in 1-2 years. I believe I have to dump DDR2 when I upgrade after 3 years or so. So I don't think it's worth buying too much RAM even it's cheap. Dual channel shouldn't be a concern. Memory seems not to be the bottleneck. Hardly any application needs so much bandwidth. What do you think?
