Hi, this is my system, http://www.expertreviews.co.uk/pcs/276940/advent-centurion-cbe1401/specifications i bought it as a refurb as it was a decent price and i was looking to upgrade my system to play bf3. So I was looking to spend maybe 200 on it hopefully on ram and a new card although please correct me if you think id be better doing something else within reason! Also has anyone unlocked 4 cores on one of these chips and would they be able to point me the right way? thanks
