As Supernova said, a HD 5670 is a entry level card, and at 1024X768 resolution, I'd say it would provide good FPS and many modern, dual core games would run on high. But games like Crysis and Metro 2033 and GTA IV, BFBC2 ( all said by supernova ), would run a bit slow. But sice it's at that resolution, then it's okay. Also GTA IV is a heavily CPU dependent game, it requires a decent quad core and a good CPU to run it well.
