ok, so the propus quad core is pretty much the same price as your phenom dual core, the ram looks good, the motherboard is compatible, but i don't know much about how good it is. You can get a 500gb caviar black for pretty much the same price, unless you're more comfortable with samsung. I've noticed that the powersupplies are pretty expensive over there, and i don't know too much about that coolermaster, perhaps someone might give some insight on that..
As for your video card, this may be within your budgeta; Eclipse Computers - Product Details
its the 5770 and is dx11 compatible and is fairly futureproof!
This should all be within your budget, although i admit i don't know how this VAT thing works.. so it may be over budget..
