I've been meaning to replace the CPU on my computer and was wondering what kind would fit on my motherboard, I ran a scan in Everest and my Motherboard is a Dell inspiron 518, with an Intel AGTL+ bus type, 64-bit bus width, 267 MHz(QDR) real clock, 1067 MHz effective clock and 8532 MB/s bandwidth ( not sure if important but im writing it in anyways). My current CPU is a DualCore Intel Core 2 Duo E7200, 2533 MHz (9.5 x 267), Anyways what kind of CPU would work on my Motherboard that is decent quality and no more than $200. Also would I have to get a new power block source or more cooling, etc?
