I found this forum from NewEgg.com's "Knowledge Base." I'm not a hardware techie, and I need some assistance selecting a motherboard and a cpu for my desktop. Current system is 5 years old--motherboard has 2 blown capacitors, and I have SD RAM. I've been told that I need to upgrade to DDR RAM, since that's what most motherboards require these days. My main questions... 1.) What's the difference between SD RAM, DDR RAM, and DDR2 RAM? Why is DDR RAM so much better than SD RAM? 2.) Current processor is Athlon AMD 1.2 Gig (from 5 years ago). I'm not into gaming, but it would be nice to have a faster processor. Since the motherboard has to be replaced, I might as well upgrade to a faster processor. Here's what Tiger Direct has suggested for me... The motherboard/CPU combo---> http://tinyurl.com/pw9qg The RAM that was suggested---> http://tinyurl.com/orxxp After the rebate, there's only a $10 difference between 512 MB and 1 Gig, so I'm going with the 1 Gig of RAM. What do you think of these suggestions? Is Asus a good motherboard brand? I'd like to go with the cheaper Asus/AMD motherboard/cpu combo here: http://tinyurl.com/lsteg It's cheaper and yet it has a faster processor (2.4 instead of 2.0). Any problems going with this combo instead of the one listed above? My current motherboard (from 5 years ago) was a Microstar brand. The 2 capacitors blew out after 4 years, and I don't want a repeat of that with the new motherboard I'm buying. What are the best motherboad brands...my options are Asus, Gigabyte, ABIT, Machspeed, and many more. Unfortunately, I know nothing about any of them. For the processor, what's the difference between AMD Sempron and AMD 64? I wish there was a hardware class to learn how to choose the best computer parts and how to install them. Everything changes so fast, and it's hard to keep up.
