Hey guys. Well, i need some help, i want to buy a new graphics card and a new power supply for it because the one i have atm is too weak. So i found this website to buy stuff from, www.scan.co.uk and i dont know which parts should i take. I was thinking about 4870 1gb.. but now sure if its worth it. My budget limit is 200£ (GBP). So can you please tell me which are the best ones? Thanks for the help guys. And btw my motherboard is not that new so i think wattage of power supply shouldnt be above 650.
