Well on a site they had a review on GFX cards and mine was there and according to that my card has Vertex Shader 1.1. Oh and is this a good OC:
Default Core speed: 250MHz
Current speed: 365MHz
Default Memory speed: 400MHz
Current speed: 415MHz
That's what I got so far and there are no artifacts yet, and the card is pretty cool, though I do have a 120mm fan with a "windtunnel" blowing cold air directly at the card.
