Fantastic Rig!


I bought this sweet machine when my laptop it the dust. After doing my research it was actually a bargain for the specs. I get quality speed and since Asus does not have third party hardware in their rigs, I felt safe about the quality. I am bumping...

I messed up royally. This is my first bought computer. When I got it, neither the VGA or HDMI cable worked. I didn't know there was a second HDMI port that worked all along; so I ended up sending it to the manufacturers (NEVER SEND ANYTHING TO...

Great computer, runs everything I've thrown at it so far with ease. If you're looking for a good, cheap computer to run minecraft with shaders, this is definitely a good choice

The graphics card that comes with this computer automatically disables the VGA connection, that is why the vga connections dont work for anybody. I've heard something about a DVI to VGA cable working, but I'm not positive about that. The HDMI ports do...

New egg is great. This is my 4th ASUS PC/Laptop. I'll continue to buy and recommend them... this will be the first strike against em. More of a foul tip really, but a strike none the less...

Great box for the price. Using it as a development box, so there is a fair amount of abuse being applied to this thing on a daily basis

came with a faulty CPU fan. Ran at 100% (jet engine) all the time. Applied the BIOS updates. Googled for about a week before I gave up and replaced the fan with a spare from the shelf. It's now quite as a church mouse. I didn't really want to RMA a box...

Amazing For Price!


using huge tv at my desk not the most comfortable but will be getting a vga to hdmi adapter to fix the problem

First off new egg delivered this in less than 48 hours got it the next day of ordering and paid for 4-7 day so big + to new egg. The computer is great runs all my games at high 1080p . the 760 is amazing . the case provides decent airflow

the vga connection did not work tried 2 wires and 2 monitors it did not work . the gpu is also in a odd position so it blows hot air straight down were it cant really go any were

Good machine


Well the first day I got it, the dang VGA port doesn't work. Not a huge deal, because I'm using an HDMI cable connected to the video card. ASUS loads a bunch of unless stuff preloaded on Win8. So I would recommend reformatting the HDD.

This computer is what I was looking for. For under $1000 it's hard to find something that can handle games on high/ultra high settings. For the games I've played so far, I'm running everything on high and get great FPS. Although the CPU does lack a...

Windows 8 and RAM. I tried to get used to it, but had to reload Win7 ; Win 8 is much more demanding on system ram, which only comes with 8GB, so you will probably have to upgrade to 16GB

Runs smoothly, runs games well, no issues with it so far. Please note that on a bunch of the other reviews giving it a lower review, they received PCs that were DOA (dead on arrival) which is a risk you stand with having a PC delivered to you. At that...

The hard drive is NOT the size mentioned. The title of the product title and the specs page say 1TB. The hard drive I received in my PC is 320GB, much smaller. Not sure if this is an accident or clever wording on the companies part

Just Amazing


I serious dont know why people are complaining with it not coming on. Also, I need a Dvi-d dual link cable to hook to your monitors. There is a plastic cap on the vga to stop you from hooking it up by vga

Asus Quality Control Needs Work


I have purchased 5 Asus products in the past and have been pleased and never had issues. Would I buy another Asus product, probably. Would I do business with Newegg, most definately. Returning a faulty product is not a pleasant experience, but the CS...

The first machine was a Christmas gift for my son, who was very disappointed on Christmas day when the computer didn't boot up. Calls to Asus( who were open on Christmas Day) were unsuccessful at correcting. I called Newegg the next day, they were very...

I received two of these models and both were unable to boot up. Not sure if the hard drives were faulty or a connection issue, but didn't want to open the machine up and void any warranty

Good computer for the price


I will update this review if I find anything wrong with the computer. For now it seems like a great purchase

Good processor ; Good GPU ; Good price ; I've been running AC4 on max settings on this rig for about a week now with no problems whatsoever. I'm slowly adding other games into the mix like Dishonored and Bioshock and this computer runs it very well...
