Bottleneck in brief means that- You gpu is being held back in performance due to your cpu, In other words,ur gpu is unable to unleash it's full potential because your processor(cpu) doesn't have enough power in terms of performance to provide support to the gpu.

No i don't think that ur cpu will bottleneck the hd7770/gtx650/gtx 750 but it also depends on the games you are playing. But with HD7750, you would be fine.

i have vga monitor................so i have to use dvi-vga adapter........will it affect my performance.........

 


Of course the HD 7750 is cooler... It's like 3 tiers lower in performance than a GTX 750 TI.
By the same measure, I could say a GT 610 is cooler than an R9 290.

The proper comparison to a GTX 750 TI in temperature is an R7 265. Not an HD 7750.
