I was going to buy a 6600GT for my computer as my 5700Ultra is starting to blow. I was looking on Newegg for the different AGP8x 6600GT models and wondering which brand to buy so i can A) get the best framerates, B) overclock it the best, and C)not have to worry about buying a new card for some time. Basically which is the best brand. Any help is greatly appreciated.
