"Will my motherboard only supporting PCI-E 1.1 be a limiting factor, and if so by how much?"
Thanks to a faulty driver from NVidia (196.75) overheating my graphics card (9800GTX) I am now in the market for a new one.
As many of my friends and colleagues know I like to spend time making sure I am getting the best I can for my budget. What this means is I will spend hours scouring the internet and magazines for reviews, articles and specifications, eventually making a choice.
This time round I do not have the luxary of time on my side, however it hasnt stopped me from doing a good bit of research, and one of the questions I had was will my motherboard only supporting PCI-E 1.1 be a limiting factor, and if so by how much?
By far and away the best article I could find on this was one from techPowerUp:
AMD Radeon HD 5870 PCI-Express Scaling
The short answer is that the performance difference between a PCI-E 1.x 16x port and a PCI-E 2.x 16x port would work out at about 2%, and as PCI-E is backwards and forwards compatible for me its not an issue.
The article is definitely worth a read, especially if you have PCI-E 2.0 and even more so if your looking at a Crossfire setup.
