Help me pick a new graphics card

[Professor S]

This example is a microcosm of a huge problem that I have with PC Gaming recently. Hardware is changing not only in power too quickly, but also compatibility. It was just a year or so ago that AGP cards and RAMBUS were all the rage and Pc makers were designing their systems to meet that demand. Now PCI and SD(?) are considered the best and now all of the compatibilities are changing, leaving many PC's in the dust.

Its one thing to have to upgrade RAM and Video Cards every couple of years, but its another thing when the industry forces you to have to reconfigure your entire PC or purchase a new one to keep up with the times.
