and none of these will be noticeably different for internet use. Personally, I like an i5 system as good compromise that allows decent performance and some room to improve. I might suggest your #4 choice to be a good start. About all that might be lacking is some graphics performance with videos. I'd see how that goes and add the video card later if you really need it. Adding a video card does come with the possibility of needing a better power supply but I'd hesitate to buy the HP with the dedicated graphics card if it had the same PS as the one without the card. That would tell me it was rather low end anyway.
I'm helping a friend buy a computer. Neither of us know much about computer hardware and I thought I could get some help from you all. Usage is light, no video streaming or gaming, mostly just surfing, photo editing, bills etc. His biggest concern is speed and I don't understand the impact on speed of 2 vs 4 core or turbo boosting of i5 processors on this type of usage. I'm listing the options he has available and would appreciate any help in selecting from mix 1 through 5 as to which you think would give him the fastest performance. There all HP so I assume they are HP motherboards. Thanks for your help. 1) i3-2100, 6Gb DDR3. 2) i3-2120,6GB DDR3 . 3) i3-2130, 8GB DDR3. 4) i5-2400, 6GB DDR3, 5) i5-2400, 6GB DDR3,1GB Video Card.
