i work with some one that has a few SSD's in his pc (2 in raid-0) and basicly what he has been telling me is that in gaming there is a noticeably differance in load times
specially with mmo games
he was telling me load times in everything else is quicker but i dont know by how much
^ basicly second hand info i havent had a ssd yet so i can not tell you first hand but like every one else will tell you the price is a bit wow for the moment, wait a bit till they come down unless you really one one now that is
