MAX CPU Speed for your Hard Earned Dollars (Retail Box)
15 September 2014
Summary: Great CPU power & punch at a very reasonable price. I've built  custom towers in the last two years using this CPU. This particular CPU comes with a heat sink fan & a sticker for your PC case (if that matters to you - if not, buy just the cpu - it will save you a few dollars). I haven't found a better CPU for the price that will outperform this one on a LGA775 (800Mhz FSB) mobo.
Summary: Great CPU power & punch at a very reasonable price. I've built  custom towers in the last two years using this CPU. This particular CPU does not come with a fan so make sure you order a cpu (heat sink) fan too unless you have a good one already available. I haven't found a better CPU for the price that will outperform this one on a LGA775 (800Mhz FSB) mobo.

Summary: I got this video processing package and it would not install on my machine with Windows XP on it. I'm fond of the machine because I do all my audio music management on it - iTunes, CD Cassette, and Vinyl transfers using the hardware on that computer. And when I got a VCR to USB transfer dongle it needed a Dual Core processor in order to run the new video processing software. Research and a little time made this one a whopping success.
Summary: The wrong CPU was shipped the first time. There is no label on the packaging to confirm which CPU, you get so you must read the tiny lettering of the label on the CPU. I contacted them and they quickly shipped the correct one with a shipping label for prepaid shipping of the old one back to them. Customer service was quick, Friendly and efficient. The E5800 was a good upgrade to replace the old E2140 CPU that I have had for 7 years.
Summary: This is a great (best?) 800mb front side bus processor! It's faster than any Pentium D, even those with faster clock ratings. It uses much less power,thereby saving you money. It also runs much cooler than any Pentium D, and works great with stock cooling. If you have a socket 775, 800mb fsb motherboard, this is the cpu for you!
Summary: This was a great processor. However the fan mounting simulated srews were terribly designed and I used my old fan. This was Intels lack of thinking though. Seller of this product was on time and the product works great.
