You have like most people up until 720 and PS4 games start being ported to the PC then you will require a upgrade... While games are still being developed for current consoles you will be fine with anything better than a GTX 460 - HD 5850 upwards. Once the new engines are in use and games are being developed for consoles with more RAM anyone with less than 2GB's VRAM won't be having a great experience... The same thing happened to 256 MB - 320 MB GPU's around the 360 launch, they became redundant. 1 GB cards have a year left or so.
