so i just bought a late 2006 black macbook core 2 duo 2ghz 1gig ram 120gb hard drive intel gma I installed Leopard on it and it improved performance for me. But I still am feeling a little sluggish when I'm trying to do more than a few things. I'll be importing photos in iphoto, have mail open, safari, itunes open usually. maybe another program-haven't installed CS3 Design Premium yet. And i experience a little sluggish performance (not at all what it was like in the MBP-that worked great,,,until i sold it!) That MBP had 1.5gigs ram and the dedicated graphics. So I'm wondering if this sluggish performance/lag is due to the 1gig ram or the integrated graphics. I don't really have the money to upgrade to the latest edition macbook with x3100 graphics or even the MBP (1499 refurb now-great deal, but can't do it now) but i do have enough money to possibly upgrade the ram to 2gigs if that will fix this issue totally. Thanks for any help!
