I presently have a 2.16ghz cd macbook pro 17inch with 2gb ram and 256mb video ram. Is it worth the performance increase to upgrade to the new 2.5 ghz c2d with 4gb ram and hires display and maybe 200gb 7200rpm/512 mb graphics? This would cost me around 2600 with tax and I am juggling it now. I use this system mostly for work and i use lots of windows virtualization software. Parallels mainly. Any thoughts and advice would be good. Thanks. I don't really game on the macbook pro but I would like to Another quick question too. Are the new macbook pros really 4gb?? or is it less than that.
