from your specs, gateway preinstalled 3 gigs of ram on it and is expandable to 4 gig. as for BUYING a fresh copy of win 7 id say naw, but maybe if you got it from say someone that sails a ship and flys a big skull and crossbones flag then id say hell yes. even with 3 gig ram win 7 x64 runs sweet. of course id recomend adding another gig. i ran win 7 x32 on 256 MB ram and it was fine. no errors. no blue screens. it'll work.
