Yes, one of the GPU's stopped working, I guess I could have been more clear about that. I am not as tech savy as you all on here which is why I came here to ask. I can tell you I bought this pc from Ibuypower about 3 years ago it's a core i7 (920), MSI x58 platinum motherboard, 6gb ram (I could add more). Anyhow; I wanted to stick with Nvidia since originally the system came with a Saphire Radeon card (I don't remember which off hand) and I had 3 out of box failures on the card. As for budget, I want to be under $300
Thanks for the help!!
