Should I buy a barebones kit for a gaming pc or buy each part?

[earnest_gamer]

Hello,
I am looking to get a gaming pc that can play most current games fairly well (although I don't need like everything HD to the max and every pixel perfect, I just want smoothness) but isn't too expensive. My question is, should I buy a TigerDirect gaming PC, (The two I was looking at are http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=2580524&CatId=4149 and http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=2311915&CatId=4149 the only difference I can spot is the processor, but so comment on that too idk what difference it would make for gaming), or should I buy each part separately and assemble it that way? Would there be a difference in cost? Is it easier to do piece by piece (I know that is essentially what barebones is but maybe you can get better parts piece by piece than just one barebones). So what are the benefits of each? Please help me make my decision. Oh and my budget is about $700-$800. Thanks, and sorry for the long post.
P.S. A new thread I posted that might be more helpful and give you a better idea of what I'm looking for http://www.tomshardware.com/forum/355419-31-blank-slate-gaming-budget
Your time is valued, thank you!

I didn't see a video card with either bundle did i miss it ?You need a GPU to game decently IMO

Oh hahaha derp I'm sorry, my technical knowledge and eye for detail is limited. So do you recommend just looking at a different barebones kit or...?

Calculate the both the prices and see which is cheap. If you are buying a kit, you cant change something which you don't like. I seriously didnt like the chassy on both kits. Also you will need a cooler, graphic card, modular PSU......

Like I said my knowledge is limited, I was just browsing the TigerDirect i7 Barebones kits. I was unaware they didn't include a GPU or etc. From what I gather it's better to just buy parts?
I have another thread which might be helpful too, it gives a better idea of what I'm looking for, please read it if you guys are willing. http://www.tomshardware.com/forum/355419-31-blank-slate-gaming-budget .Thank you very much for your time.

For future gaming would an i5 be good too? Because I don't want to overclock so I don't really need a K model, but I just wonder if an i5 would be as good as an i7 in like a year or two for gaming?

Well in order to build you a gaming rig that will last you need about 1000 that would be including all the stuff like keyboard mouse OS elect

i3 is for video proscessing, i5 is for gaming, i7 is for both, i really hate having to post this, but you dont need i7 for gaming.
