I did a lot of research and comparisons with a lot of other vendors and felt this was an exceptional value. The first system came and was DOA. I was worried I had made a huge mistake. Called ASUS and they wanted me to return it them for repairs--no specific return time. I called Amazon and they drop shipped me a new one that arrived in about 36 hours with a UPS return for the first one. The new system works superbly. I have an ASUS PA248Q monitor that is very good as well. So far this was a very good choice. The machine has a lot of highend for most people who aren't just looking for a super hot gaming machine. So far all games I have work well though.
Addendum: In the process of ordering this system, I discovered that Amazon had some faulty specification information regarding some of the ASUS models. It appeared that the manufacturer's product description for one of models was inadvertently inserted for another model. I think it is understandable to have such an occasional mix-up given the huge number of products being sold online, but it made things very confusing. I found it very important to compare the manufacturer's website information with the product description at Amazon to make sure the item ordered was correct.

I did a lot of searching and this unit with the i7 processor, 16GM RAM, fast hard drive, and discrete graphics card included came up looking like the best value for me. I bought it to run 4 1920x1080 monitors for trading. It came with the motherboard integrated graphics disabled, but the BIOS has a very user friendly interface to change the graphics choice to both integrated and discrete graphics. The integrated graphics defaults to 64MB total memory so should be ok for me, but probably not for a gamer. There is only one PCIe x16 slot, so would not be able to add a second graphics card. One can hear the fans but the level is not objectionable.

I have had generally good results with asus products and this is no exception if you're willing to live with its limitations.
First off, my mistake, this system does NOT have a wireless adapter. Somehow I missed that in the description.

Secondly, the Nvidia GT 620 is too under powered for anything other than business graphics or SD movie watching.

If you decide to upgrade the video card you'll find the system has two 16x slots, however the second slot is too close to the edge of the mother board and does not provide clearance for motherboard cable connections (USB I believe) or cooling fins or fan on a video card because of the slots proximity to the bottom of the case.

Using the first 16x slot for a video card upgrade (where the 620 comes installed) will block one of the PCIe short slots.
Additionally, if you upgrade to virtually any gaming capable card you'll need an additional PCIe power cable - which is not available on the 350w power supply included with this system. Depending on how beefy a card you get you can either get a molex to PCIe adapter or (more likely) replace the power supply with at least a 450w source. The vast majority of the aftermarket power supplies will have the required power cables already built on.

Since the system wasn't DOA, I couldn't return it under Amazon policies and get something a bit more expensive with the specs I needed. Make sure to read the detailed specs and buy for tomorrow.

Live and learn!

I bought this computer in June based on the specs. I had no problem for 2 months but then the computer started turning itself off by itself. I had no problem with that until it started to do it several times a day in October. First I tried to reset it to factory settings with no improvement. Then it contacted ASUS tech support and they suggested I change the settings so that it never turns itself off. I changed the power outlet, power cable, even reset it again but nothing works. About two weeks ago it turned itself off again for the fifth time that day but this time I could not restart it again, so I left it turned off over night, and in the morning it restarted and run for 3-4 hour, and the problem started again. To me it looks like an overheating problem. The reason I give only one star is that ASUS will not replace the unit. They want me to ship it to them,wait for 5-7 business days and then I may get it back. This is unacceptable as I use the computer for work, and I need a replacement before I send it out. I solved the situation by buying another ASUS computer and when I get mine back, I will returrn the new one to the store which will return it to ASUS to be refurbished. That is my small revenge. I recommend you buy ASUS only if you do not have other choices.

This is a very nice PC. It's fast, boots quickly and is attractive. My one complaint is the instructions are not adequate. I connected the HDMI cable from my monitor to the HDMI port the instructions specified. Got no signal on the monitor no matter what I did. It took a call to technical support to learn that the HDMI port described in the instructions is disabled if the computer has a discrete video card installed. If it does, you have to use another HDMI port near the base of the computer, which I didn't notice. I thought the thing was DOA. Explaining the video card issue in the instructions would have taken a sentence or two.

My call to tech support, however, was answered in less than a minute and the tech knew immediately what the problem was. He stayed on the line to make sure it was fixed. So despite that small glitch, I am good with this Asus computer.
