I'm a hobby gamer and I'm looking to improve my computer, I currently have an AMD HD 6450 silent graphics card installed but I am looking for a new processor/motherboard bundle on a budget. My friend recommended this (http://www.overclockers.co.uk/showproduct.php?prodid=BU-188-OK&tool=3) but I don't really know what I need. My current components are an AM3 motherboard (don't know the specifics) and an AMD Athlon II X4 processor. Any advice would be great, thanks!
