Yup, invest in the monitor! Even at 1920x1080p the card can more than handle the extra 15% resolution. Left for dead 2 ran at a consistent 60FPS (v-sync enabled) with everything maxed (AA at 4x, AF at 16x). I just recently upgraded to the 6870 to future proof myself and installed the 4870 in my second PC. Emperus is right – 69xx is coming shortly, so you may be able to get it on sale when you're ready to buy!
