I am looking to upgrade my graphics card to a 7970 or something similar but know for sure my current cpu will bottleneck it (Athlon 750k). I don't have enough money to buy a new GPU, CPU, and motherboard so I was wondering if I could buy the gpu now. It would still give me better performance than my current 7770 would, correct? Could this damage my components? I am just wondering if bottlenecking means your gpu hits a certain limit, or it doesn't function correctly at all. Thanks!
