My old computer had a 2.7 Ghz processor, and 4 gigs of RAM. Due to security concerns, I upgraded to Windows 10. Computer got super slow in spite of changing some settings based on online tutorials. Ordered this machine from JSM Computers. Faster processor, and 16 gigs of RAM makes this machine blazing fast for my casual household use. Solid state hard drive means almost instant boot up. Machine arrived in excellent condition. Clean, and perfect function. Easy set up, and Windows registration went smooth. Seller emailed post order with phone contact info in case of questions, or issues with the product. I strongly recommend the seller, and this product.
