Hi: I've looked at Intel web site and I'm trying to decide whether I should get an I3 or I5 processor? I use my CPU to do all basic functions email,use word,excel,surf the net,do a little photo editing,rip movies,music,etc . I want to use it as a HTPC now also run itunes better that my current CPU does(specs on current CPU are as follows: 2.66ghz single core,1.5gb ram ddr400,gforce 6200 video card 256mb,generic sound card ) running Window XP Pro. I'm trying to decide between a I3-540/I5-660 Intel based system would be a major step up from what I currently have but would it be enough? I'd use 4gb of ddr3 ram,a good video card with 512/1gb, sound-blaster audio card,etc. My question is should I get an I3 or I5 processor for what I'm going to use it for thanks for any help!!!
