A big Hi to the community. Well, I have decided that I'd probably buy an Asus HD 7770 2 GB DDR5 graphics card alongwith 8 GB corsair ram from Amazon. But when I came to know that my now-three-year old PC has standard fan and heatsink (73 W), I became a bit skeptical. Can you guys tell me wether my 73w standard fan and heatsink be able to withstand 8 GB of ram and the power of a HD 7770 when I play F1 2012 on it ? Will it overheat or remain fine ?
