Summary: I have updated the Ram from 6GB to 12GB, changed the HDD(now is 2nd drive for storing files) to a SSD( sandisk 256), and bought a new GFX card. This baby is a beast! I got it 2010 and still use it today.
Summary: Have had the DX4840-07 for ~ 5 months now. Runs smooth as silk. Great for intensive accounting & photo software. Had my last Gateway for 8 years before upgrading. Love Gateway. Never had any problems. Great service from Amazon.
Summary: I needed to replace a 3 year old office desktop with a noisy fan (which I will repair when the transfer is complete.) The Gateway SX2850-33 got a great review from CNET but it seemed cramped, so I looked further, and this model met my needs. (The -11e model was about $100 cheaper but had an i3 processor). Lots of memory (6GB) and disk space (1TB), and an i5 processor with Windows 7 64 bit.
Summary: I actually bought this because of my recent problems with Dell system quality, order fulfillment and customer service. I found good reviews about this system on cnet, so I gave it a try. It sets up easily, is super fast and super quiet. My husband loves it. You have to set up your own recovery disks. It takes four dvd's for system default backup image and drivers and one cdr for recovery boot disk.
