So I've been rocking the rig in my sig for a good few years now and haven't had any real need to consider upgrading. I don't tend to buy brand new games, I only have a 1280 x 1024 monitor currently etc. so am not pushing for premium performance. Nevertheless, to get involved with the newer games at a decent framerate I suspect it's about time for me to upgrade, though I'm only really considering the GPU, not the whole rig. I don't mind buying used, but would kind of find it reassuring if the card I was buying wasn't obsolete - i.e. can still be bought retail too (though ultimately, if there aren't any currently retailing cards that are compatible, or if buying them would be overkill for my system, then obsolete cards will obviously be the way to go). Thanks.
