I've saved up about 500 euros and Im looking to uprgrade my pc (gpu and cpu). so my question is which gpu and cpu are the best for the money in my price range. and also wondering if those new parts will be handled by my 450W psu. Current specs- i3 4130, GTX 650 2GB, 8GB RAM and motherboard with i think lga 1150. new cpu needs to go on the same motherboard since it's an useless expense to buy a new one. thanks
