Discussion: Battlefield 3 / Battlefield 3 - Technical Support & FAQs - BF3 Video Card & CPU performance comparisons - 3 great articles that compare graphics cards and CPUs for delivering frames per second (FPS)
This thread could be pinned as a Graphics card guide for TGers looking to upgrade. It would make things easy...
Something to keep in mind is that it is hard to verify what drivers were used to perform the benchmark. Drivers are always continually updated, so performance will usually improve for the newest generation of cards. I expect the the AMD cards with have their MSAA methodology improved to be more in line with what it should be.
GTX 470 here...Happy to report I'm happy with the performance. I hate turning on the FPS OSD so I have no idea what I"m hitting for min's and max's. All I know is it's working well with no stutter or lag so that's good.
Although my graphics card is 3rd from the bottom on the list I don't have any complaints so far about about performance. I consistently get around 40fps at 1680x1050 as the chart indicates. For those of you looking to save some money, a cheap-ish GTX 460 offers adequate performance.
