I have a pentium 4 processor that i took from a Compaq computer that was given to me. I'm going to use the stock case, fans, and power supply for now. I have a seagate 37gb 10k HD. The processor is a Pentium 4 SL5UW 1.6ghz/256/400. I also have the Mobo and everything else that comes from a stock compaq. Should i start from scratch with the CPU or keep this one? Is it any good at all? Would i be better of spending the money and getting a new CPU? This computer is going to be used for multitasking, surfing, and the usual. Nothing over the top. Some gaming but nothing out of the ordinary. thoughts? This processor is old but should i keep it and just replace the board?
