Hi guys, I've been tasked to spec a mid range full system for my girlfriend. She wants to spend around £600, £650 absolute tops. I've tried to keep it around the £600 at the moment but if any of you suggest something thats worth the extra £50 then i'd be happy to include it. The main purpose of this machine will be for general day-to-day work (office etc), photo management/editing, video and casual gaming (i.e. sims 3 when it is released). The spec i've done so far is below, she's keen for a smaller case so I've gone for an M-ATX case / motherboard. Anyways to cut to the chase, what do you guys think? Any glaring omissions? Any schoolboy errors? Any recommendations and/or advice would be greatly appreciated, thanks in advance.
