Well, I know that the difference between 875p and 865 is mainly just 875 has PAT(Performance Accelerating Technology)...... Its alittle faster, but most vendors have copied whatever PAT really is and 865 chipsets are very competitve If you can get 875, but its not a neccsity As for the letters after 865, I don't really know I know the designate features for that chipset, like onboard video, etc., but I don't know what letters go with what features
just make sure you do a burn in. (That's leaving your PC running for at least 48 hours to allow the peices and parts to expand and contract and fix nicely.) Most major hard ware problems will show themseves in the first 48 hours.
thanks all who helped me out so from what you guys said everything seems great just need to get a better mobo oh yea whats the difference between socket 478 and the 700 something socket?(yes i am new to computers things)
@xotix
sure i will tell you when i get it might take up to 2 weeks though
the socket 478 is the pin package that the cpu is classified under.. so if u have a socket 478 chip you cant install it in any other mobo other than one that supports the socket 478 package
