I think it looks pretty Solid. If i were you i would just go with 8gigs of RAM 16 is probably a little overkill for gaming. (if you dont mind spending the money then go for it) other then that. Looks like you have the right idea.
looks good to me and i agree with tenaciousk on this get 8-16 gb ram
Great! I've changed the ram to 8gb and saved 40 quid! I will now order, thanks guys!
