no it shouldnt be, only in very cpu demanding games that would maybe be the case (like say 64 player maps in battlefield 3, if you have bad performance there its probably the cpu). in most other games you wont have a bottleneck because your cpu has good gaming performance, no need to worry :) you can download gpu-z and check how much your gpu is being used while you play a demanding game. if its stuck at 40 % when it should be 100% you have a bottleneck.

Palit and Gainward are typically European brands. I personally wouldn't recommend getting this. Since you're clearly from North America, the prices of the Radeon HD 7950 and this are the same for us, and I would highly recommend the 7950 over this card. The 7950 is faster, has more VRAM that isn't gimped by a low bus/bandwidth, and is a great overclocker. If that interests you, I can make a recommendation, this one. Its clocked at 960 MHz out of the box, higher than the Asus DC2 TOP. Sapphire is also the best brand for Radeon cards, and from what I here they have excellent customer service. I wouldn't use the Trixx utility if you go this route though, I'd get MSI Afterburner, its got better features and is pretty easy to use.

We? Is that your site? :O
