The only thing you need to know is that your card will be obsolete the minute you walk out the store

then why is it that i didn't upgrade my graphics card for the last 3 years? new and more powerful cards will always come out, thats part of PC gaming, but that wont make your card obsolete, unless you are obsessed with having the most powerful rig.
