Hey guys, I'm kinda new to the works of computers, and this has probably been asked before. My main question is, would it be better to upgrade from a single core(Celeron D[Yeah, I know it's old]) to a Core 2 Duo, or go with something else, say newer tech, though I am on a budget. I'm not looking to spend any more than $600-$700. Also, my primary uses will be web browsing, multi-tasking, and gaming. Your adice would be great guys!!
