Both cards are second hand. 1. Powercolor HD 4670 (PCS), 1Gb DDR3. Price - 50$. 2.XFX GeForce GTS 250, 1Gb. Price - 75$. The prices in real life are not us dollars, but I put them in dollars because it's easier to understand, then putting it in swedish SEK. What I would like to know, is which one of these cards should I buy? Which one is the more powerful one??
