I built my own rig about a year ago and I'm looking to upgrade my graphics card. Right now I currently have a Sapphire Radeon HD 7850. I didn't do enough research for my video when I was about to purchase it. I don't do a lot of gaming but I do occasionally, I mostly do video editing. I use After Effects, Cinema 4D, Photoshop, and all that. I want to switch to Nvidia because of CUDA. I know ATI cards don't have CUDA and such. So basically what I'm asking is what is a good Nvidia card that is a all around good card around $250. I'm also looking to run SLI after I buy this new one.
