Looking to buy a gaming pc [$800 budget]

[jcope]

I do not know anything about this forum, I hope this is the right place to ask for information like this. I did not know of any computer forums, but I found this one. I'm looking to buy a pc already built for about $800. I am not computer-hardware savvy. I have found two options that look like good options. The only reason I believe this is because of their reviews. Here they are

I apologize if I am posting this in the wrong section or if I am not providing enough information. Any help is appreciated.
I do not want a monitor included with this. My current computer is a laptop and can only run League of legends [computer game] on low settings with 25fps. I could hope to be able to play more pc game with my new computer with better quality. If I need to provide anymore information just let me know.

They all come with fairly weak graphic cards. http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=5653741&CatId=114 bit more expensive but you get a 660 with it.

Thank you, how can I tell on my own if the graphics card is good or not? are you looking at the brands or is their a figure I can look at?
edit: also what is the prime factor in the pc that lets it run ultra settings, but also with high fps. Is it the processor that deals with the fps and the graphics with the quality?

By consulting this guide: http://www.tomshardware.com/reviews/gaming-graphics-card-review,3107.html click on 7 for a hierarchy.

In theory you *could* buy one of the models without a GPU and put one in yourself. The problem is that these manufacturers aren't dumb either, and purposely ship the models with low wattage power supplies with 300-400watt, meaning in most cases you need to buy an powersupply as well (and redo the cables). Adding ~$60 to the GPU purchase price.
