I think my 6 year old desktop PC is could be on it's last legs running vista. (just not speedy as it used to be, despite virus scans being clean) My question is two fold: 1). Is it worth it to just replace the HD, keep the current PC with all my applications 2). Buy a new Intel based faster model since the holidays are coming up? 3). How long do desktop computers typically last? I run a few programs (Dragon 11 for one) and the responsiveness just isn't there like it used to be. Opinions are welcome.
