Would this be good for Photoshop? Not high level Photoshop, but basic. The rest would be MS Office and browsing which I know its good for. Also I would upgrade the ram to maybe a total of 8GB (hopefully its just one 4GB stick inside) and possibly upgrade to a SSD and turn the 500GB into an external drive. Also would you suggest getting Dell's extended warranty, or maybe look for a Squaretrade deal? Thanks!
