Bought a 4 series card, then a 5 series, and plan on getting a 6 series. so its annual for me. Don't plan it that way, i just get so excited for the new cards. Now i know im doing that though, i'll probably stick to the mid-range cards (ie, 6770 or nv equivalent). since upgrading from a 4890 to a 5870 was not such a great idea, especially since i never use it anymore. Will be selling my primary rig and getting a 6770 for my HTPC, which will become my main gaming rig.
