I have about a $1400 budget. This will be my first build and I'm just wondering if this is going to be the best for the amount I can afford and if all these parts are compatible and all work together (mainly questions about the speakers/harddrive because "OEM" really confuses me). Another big question I have is if i should stick with the 7900GTO that i have right now or go to the 7950GT. These are the current parts that I have in mind. I'm also thinking about Swapping the CPU/mobo for Intel ones... like an E6400/P5B, or E6300/P5N32 SLI. I'm not sure if i should go for an SLi system with a weaker processor or vice versa.
