560Ti SOC 1GB is the cheapest of the three cards at €250.The Sapphire 6950 is the cheapest of that range available for €262 along with an XFX model which is the same price both 2GB of memory.I've heard of the Bios flash that is possible with these cards to bascially unlock it to a 6970 but ive also heard of the dangers that accompany it.Is there another way to unlock the shaders of the 6950 without raising the TDP to 6970 levels? Or should i just go for the 560Ti? Also these cards are going to be part of a brand new system I am building myself with Ubuntu as an OS so if anybody has used it or any experience with it plz tell me your rating of it compared to Win7 and its €100 price tag.
