Well I bought a barebones kit a few months ago and want to upgrade. I have a MSI PM8M-V Via Socket 478 MicroATX Motherboard and am thinking about going with something like a 3.4 ghz prescott. I am upgrading from a Intel Celeron D 340 2.93Ghz and 1 gig of ram. From what I understand Celerons are bad for gaming. I want to get some more speed out of this system without building a new pc. Can anyone give me some good advice for a chip to buy.
