ive got a pretty terrible system atm and im starting to slowly upgrade it now, the main thing letting me down is the graphics card so thats what im upgrading first. im planning on doing it in this order, graphics card > motherboard + processor + ram > cpu cooler > then little things like better disc drives and an SSD, i currently have a Sapphire HD 5450 which is pretty much useless for anything other than minecraft, im looking to spent around £90 but dont mind going upto £110 if its really worth it ive been looking at an AMD radeon HD 7770 but was just looking for some expert advice
