Yes. But it might not be the case here that's why i asked the questions above. If he is getting the same fps with different graphic settings it's not because the card is not that good of a performer, when he increased the settings he should of lost fps not stay the same. Just saying.
You edited wile i was posting. I won't search for an article, but a 5750 is comparable to a 4850, was there no bottleneck, ever, back in the days when people ware buying that card as a price performance best choice? The speed of the CPU has an impact on most video cards when it comes to gaming.
no, the bottleneck refers to the fact that your CPU cant process the information faster than the GPU can send it. and if this is ever since you installed windows 7 over vista, then yes, there is an issue there, and not with your CPU being a bottleneck. is there any way you can try your card on a different computer and see if that is really the issue, and not something that occured when you went to windows 7?
