The reason i bought 4 is i do quite a bit of video editing nowadays, and my swop file is commonly 3.5GB when i have 2 gig installed, so i figured another 2gb would be of help there at least.
Cant wait to try overclocking it as ive heard these 2.4s will go to 3ghz comfortably, but want to get the build finished first and my raid array setup properly before i start pissing about. LOL
