Luckily I bought an extended warranty since my card fried. My original card was GeForce 8800GTX 768mb. The company replaced it with GeForce GTS 250 512mb. I was concerned about being given a replacement card with less memory. I was told that the new card was better specced than my old one. Should I be concerned or try to get them to give me a better replacement? Will less card memory affect performance in any way even if the card is faster?
