I do not see a real point in upgrading yet. Wait a year so you can see what AMD has in store and hopefully Nvidia will price accordingly with their 800 series. --- BreadGolem: We never killed Native Americans, they got sick!
Read the recommended requirements on all the games out you currently want to play. Buy the best one, and the next time you need a new card you'd probably save money. --- 'The Intel i7-3770 if you're rich, the i5 2500K, i53570 or i53570k if you're doing okay, the AMD A10-5800K or i3 if you're just about hanging in there.'
I would wait one more year. The 580 is dated but not outclassed yet, unless you plan to sell it for cash. --- Snake: There's no happiness found in death, no peace either; I'm leaving here alive, because a strong man doesn't need to read the future, he makes his own.
Personally I'm waiting for the GTX 880 to come out, which should be in around half a year. It's estimated to cost the same (if not a little less) than a 780 costs now, and should be a much better upgrade. --- The world gets weirder every day. PSN: Marioface5
Who told you that it's good but dated? My 570 is still very solid, so your 580 should work very well if you're willing to sometimes lower some SSAO or tessellation. --- Antec Neo Eco 620w | Gigabyte Z68XP-UD3P | i5 2500k 3.3 Ghz | EVGA Gtx 570 1280 Mb | 8 Gb DDR 3 1333 Mhz | WD 1 Tb 7200 Rpm SATA 3 | HP 2011x 20" 1600x900
