i have a dell vostro 220s with a core 2 duo e7500 cpu
could i upgrade the mobo to this http://www.newegg.com/Product/Product.aspx?Item=N82E168...
and upgrade the cpu to a intel core q9400?
i know that i cant OC the e7500 on the stock dell mobo and the q9400 doesnt work on mobo either
will i be able to OC any of the processers with the new mobo?
lastly, is the cpu upgrade worth it?
Your new motherboard and new CPU are compatible with each other and you can overclock both CPUs on the new motherboard only not on the oem one. I assume your computer case is a micro atx one and so the board is compatible, however if you are overclocking I urge you to buy another computer case since the current case has terrible airflow and offers inadequate cooling for CPU coolers and in general. The upgrade is worth it, I too have found the performance from dual cores to quad cores to be quite a difference (I changed from an Athlon II X2 220 to a Phenom II X4 955 BE). I can convert files much quicker, I can multi-task more often without worrying over CPU load and much more. Just a word of caution, you computer case may be special and not have a universal design which will allow the changing of a motherboard. Take a look at the standoffs and look at the motherboard in the picture and try and visualize if it will line up.
