I have a Dell Dimension 8200 desktop computer which is powered by Dell Dimension motherboard and an Intel pentium 4 processor running at 1.8 ghz. A friend of suggested that I get the processor upgraded and suggested a Intel SL7EY processor running at 2.8ghz. Hence I want to know if the processor will work on my computer or not? Also will upgrading the processor improve the speed of the computer? Please share some useful information about this issue. Thanks in advance.
