to OP. bw sure to get an nvidia graphics card if your going to be using editing software like adobe, since the program takes advantage of nvidia's cuda tech which will speed up the process while working on your projects in photoshop, and maybe more of the other programs that you stated you will be using. if your not going to be playing any games on it then you could most deffinatly get a gtx 650 (non ti version as it really wont make too much of a difference in adobe. you can get one for like $110, and put the money saved into an ssd drive, which will also work well while doing your sork. it will speed up the process while rendering since it all being done on a ssd compared to a standard hard drive. i do similar work and an ssd deffinatly helped things out. you may want to get both a ssd and hd. so you can save all your work when its finished on it and free up your space on your ssd drive. an i5 3570k would be a good choice, and a gigabyte board will do well also. maybe a ud5? or higher. if your not going to be gaming on this computer than you really dont need any higher of a card than the 650. adobe recomends to use a card with cuda cores, and 1 gig of memmory on it, or more. spending $200 on a card when your not going to be gaming on it is silly. and AMD cards do not support rendering in adobe products, so there is absolutly no point in gettting the amd cards when what will work for you is the 650.
here is a nice one to consider. and to be honost, you could probably get away with a gt 640, and put extra money towards an i7 since you are doing editing things. but overall, id say an i5 and gtx 650 is a good place to be for your needs.

if it were me, and having the experience with my pc in the description below, id just get an ssd, hd, i7 of some sort, and the gt 640 if ALL I WAS DOING is editing/rendering jobs for work, and NO GAMING. the i7 3770k and gtx 670 i have are great, but the card is WAY overkill for editing. great for gaming, but not needed for editing. a gt 640 looks to be where you wanna be, with an i7, or gtx 650 and an i5. i feel you will benefit more from the i7 and gt 640 though
