I have an old 1.4 pentium 4 pc right now that I need to get rid of, because I just want something that is going to be faster. I have $800 to spend on the tower alone, because I already have a good monitor. I also already have a harddrive to put in there, so I wont be needing that at all. I plan on using the PC for the basic Office stuff and internet, but I also want to run my TV through it with a capture card, so I want at least 256MB on the GPU, and a dual-core, preferably AMD x2, or opteron if anybody has instructions on how to over clock it. I also prefer asus mother boards because of their reliability, but I'm open for anything. What would you guys recommend?
