I think Dell uses Intel mobos, but 2017 is 4 years off, so I wouldn't be bothered about Asus. I use mostly Intel CPUs, but I've got a 5 year old laptop and a 4 year old desktop with AMD CPUs that're still running fine, so I don't think you'd go wrong with either one. The AMD CPUs are certainly cheaper. I think I'd be at least as careful about power supplies as I would be about mobos and CPUs.
Good luck.
I am planning on building a desktop computer and am now in the process of doing research. Back in the late 90s I built my first computer and used an Asus mobo. Then in 2003 I built another computer which I am currently still using. (Processor - 2.40 gigahertz Intel Pentium 4, 8 kilobyte primary memory cache, 512 kilobyte secondary memory cache, Not hyper-threaded. - Main Circuit Board - Board: Intel Corporation D845PESV AAA97671-107, Bus Clock: 133 megahertz). It has not given me any problems and is still running practically like new. Since I have had such good luck with this combination of Intel Mobo and Processor I really would like to continue with an Intel set up, obviously their newest products. I am also aware that Asus makes a very good Mobo and so far my research does not rate Intel's Mobo very highly. I also read that Intel will stop making desktop Mobos in 2017. I am also aware that just because I had good luck with Intel's older product is no guarantee that I will have that kind of luck with their newest products. I am in a quandary and would appreciate your input on motherboards and CPUs.
