whatever model computer you are using...get any but that kind...lol...really though...you should think about what you want to do with your computer...gaming...or just internet and e-mails msn ...or video and audio intensive work...or business...keep these in mind when shopping and you'll be fine...sorry if that's not much help but all I got at the moment...a good rig though should be fast enough to do whatever you need it to...take care my friend
