I would stay away from packaged deals like this.. although this is actually one of the better i have seen of late.
I build my own pc's as well as those of friends. The thing i look at is what my budget is, how long between builds its going to be, the current/future technology, and look into chips that can be easily overclocked to give better performance. e.g. i have a q9400 2.66,but overclocked it to 3.6 and very stable, so i saved myself about a 100$ just by doing that. Also what are your future plans, is it just for gaming? what new games that are coming out that your interested in playing? will your rig have enough power? etc. If i'm on a budget i usually buy the low end of a new technology because it will allow me to reuse some components in future builds.. Think through some of those things and if you need some help send me a PM. In terms of those new chips i haven't really looked into them,but if it says doesn't need a gpu then thats a first for me, i would think it needs some form of onboard video.
edit: i found some info on testing you should read,seems that it will run fine but the traditional cpu/gpu is best imho.
