Hi, can somone suggest me a good graphics card that wont cost loads but still has fairly good performance? I was thinking a HD 5870 since there is one locally which I could bargain down to around £20, but will anything bottleneck? I heard the X5450 is not to be paired with anything more powerful than a 1050 Ti and the 5870 has performance inbetween GTX 750/ 750 Ti? What do you think about this?
