So I am interested in getting a new gpu so i found one that is good and cheap the Amd radeon 7770 2gb because im only gonna be looking for mid to high performance not much so my motherboard is a MSi 2AE0. I want to know if I buy the gpu will it work and or fit and will it bottleneck if possible because my cpu is 3.3 ghz quad core amd 5500. oh and my psu is 300 i think looking ot upgrade that any suggestions are welcome!
