This computer runs beautifully


This computer is an excellent cost effective package of a medium performance gaming computer. It handles most all games perfectly. The hybrid drive makes for an incredibly fast boot-up and programs also launch incredibly fast. I was hesitant about the...

Fast Boot ; Great Graphics ; Swag multitasking ; Silent ; Handles every game that I've thrown at it so far

A 3.2GHz processor might not be enough for some? It is perfect for me though

fairly fast

From NewEgg today in my email inbox ; We checked the specs for the item 83-266-528, and confirmed that it has two VGA ports and one HDMI. That is 3 video ports in total ; NOPE this is still wrong. My gosh - this has been an absolute nightmare. I just...

Graphics Card Wrong


As expected, overall fast and quiet

BEWARE ; The graphics card listed states "NVIDIA GeForce GT720 2GB DDR3". I researched this on the GeForce website as NewEgg only listed back ports as (1) HDMI. GeForce website lists the GT720 to have 3 outputs HDMI, D-Sub, DVI. What was shipped has...

Lenovo Desk Top PC


Will go to New Egg first time, every time. Their Customer Service has treated me exceptionally well!!

Easy set up. Booted and worked first time. No issues so far. Good price. Fast delivery. NewEgg Customer Service is 1st rate! I'd give it 5 eggs but it has been running only 3 weeks and nobody is perfect!! But New Egg is real close

None yet. Working fine right now

7 in 1 media reader Not for photogs


Dedicated graphics GTX 750ti, Windows 7 with option of Windows 8.1. I didn't have the time to make sure all my programs were ready for Windows 8.1 so it was nice having 7 already loaded and when I get around to it I can upgrade to 8 for free

I was so wrapped up in looking at the internal specs that I didn't even check to see what media card reader it had. It can't read my CF cards for my Canon SLR or my MicroSD cards unless I put them into the SD adapter. I am constantly transferring from...

Powerful Sytem on a Budget


If you want something for a great price for right now this is the machine. It comes with a free Intel Starter Kit that I didn't care about until I actually installed the games and played around. GRID keeps me busy in my off time :)

The specs of the machine are great. This really doesn't lack much of anything. The i5 processor is a strong processor that does not lug down under any load. The 8GB of DDR3 RAM is enough for me to run all of my design software at once. The GeForce GTX...

The one and only con that I can "see" is from the spec sheet. It has a low power power supply. I haven't experienced any issues with that but I do plan to upgrade it since you can find decent ones on here for just over $40. Taking it from 230watts to...
