Great build for gaming right there and can even fit an SSD and Blu-ray disk player. AMD processors are the shiz for gaming I go with them everytime. The processor and socket are brand new (came out like 2 weeks ago) so they are "very future proof" as some like to say. Also, it's an APU no need for a discrete graphics card. If you want to crossfire just add a compatible card. The A10 is extremely overclockable and actually has a built in Turbo Overclock that raises the cores to 4.2Ghz when needed. If you plan to do a lot of gaming and stuff use this one. It can even run BF3 on ultra settings (forgot what resolution) over 32 FPS. As long as its installed on the SSD of course.
Well in my area (where dollars are not in run ) there's like 2K difference which is probably 10-20 dollars ..if I calculated correctly .. or the seller told me the wrong price I5 is 19000 and I7 is 20000 ..that's like 10 dollars I guess .. well then again am weak at maths
