Looking at my specs below, would it be worthwhile to upgrade my video card now or wait until the next generation of cards? I try to run all of my games at 1920x1080 with all the eye candy enabled but i've been finding that the 560ti is coming up a little short in that department. Is this a result of having only the 1Gb version? I'm not super loyal to any brand so i'm open to AMD or Nvidia. I'd like the card to be in the $275-$300 range at most if it makes sense to upgrade. Thanks.
