Hi, I'm thinking of doing the step up program from my 9800gtx+ to a gtx 260 core 216. I really dont know what the difference would be between the 55nm or the 65nm. I heard the 55nm sucks up more power and puts out more heat, but I dont know if thats true. I dont plan on getting a sc or ssc version because I can do that myself and save money. Just the stock version, but I probably will o/c more than the ssc version at sometimes. So I guess my question is, which version o/c's better? 55nm or 65nm? and which is better on power (that may be the deciding factor for me)?
