i have just built a system with i5-3570K (it was the cheapest in amazon), asrock H77M, 8gb ram, XFX P1-550S-XXB9 PRO550W PSU. To save dosh I fitted my 2 year old geforce gt430 1GB GPU. Now I am thinking of changing it but cant afford more than about £65 - £70. So is it worth changing with a limited budget - if I change will I notice any difference. I dont play modern games (Oblivion is most up to date) but do a lot of photo and video editing. Any advice would be appreciated.
