The most frequently asked question on forums these days have to do with the new PCI Express 2.0 interface. Is Intel's P35 chipset good enough, or is the X38 the better choice Compare Prices on x38 Motherboards? How much more performance can you expect from an upgrade? Do current graphics cards even really take full advantage of the PCI Express interface?
Recently, we've received some critical reader feedback saying that using an Intel 975 chipset with its "castrated" PCIe interface to test a modern dual-card HD38x0 setup could no longer be considered up-to-date. We've taken this suggestion as an opportunity to switch our lab over to newer hardware, so that all future ATI Crossfire testing will be conducted on motherboards using the X38 chipset. (Thank you so much, kind and critical readers! -Ed.). To determine what benefits this changeover actually brings us, we have run a few specific tests that focus on Crossfire resolutions that actually show a performance improvement. In the best case, we got 20 percent more 3D performance out of our Crossfire setup.
I read an article that was comparing PCIe cards into slots that were only 8x and 4x.
I was wondering if that means you can buy PCIe 2.0 cards and put them in a x16 slot (and still work; but with degraded performance).
