Hi, I have this confusion about video cards. First of all there are so many different specs to look at. Clock Speed, Memory Clock, Memory Bus, Band Width, Memory, Stream Processors, All these are really confusing for me Because I currenty have a XFX 8800GTS Extreme (640MB) and I want to up grade it and am looking towards 8800 GT the ALPHA DOG Extreme Edition...Is that a good choice or should I stick to what I have right now? Or are there any other Choices? Suggestions Anyone? Thank you, Brian.
