They will run. Not at 1920x108, but at 1200x800 they will run. I have one in a Core2quad system with Q6600 and it works at lower settings with many games.
by very slow we are talking about perhaps <10fps with that card. But 2Gb is reasonable. The overclocking is irrelevant, you need something like 100x more power.
they might run. when i say run i mean you may be able to launch the game. but it would be a non-experience trying to actually play any of them even overclocked
