I would like to get a video from the Raedon HD 7000 series, more specifically, 7700 or 7800. I managed to find my computer's specs online and want to ask if I were to get a new card, would I need to upgrade anything else, like a better PSU, or a better CPU to prevent the card from being bottlenecked. I don't mind if it's bottlenecked a bit, but I would like to run Skyrim (as well as BF3) on high or ultra and be able to play Witcher 2 more smoothly. The computer specs can be found here on the official HP site. I hope this is enough information to answer my question. If I have forgotten or you need anything else, feel free to tell me and I will update ASAP.
