Sorry for my question if it is lame , but I'm a noob when it comes to hardware stuff (i'm a software guy myself). I want to upgrade my CPU from the 1000Mhz Intel Celeron with 810 chipset that is to something newer (like better than Celeron). I have a Intel Corporation Whitney System CR Board on this pc and I don't understand how you know what CPUs are upgrade compatible with your motherboard. Can anyone tell me what CPUs I'm limited to in upgrading or where I can find this information. I looked it up a bit on the intel site but couldn't find quite what I was looking for, figured I'd be better off just asking somewhere. Thanks for any help guys/gals.
