I am a fisrt time poster and I have a question for this forum about mobile gpus. I recently purchased a prostar clevo p370em with gtx 670ms sli and I was wondering where I can sell these two graphics cards and get a 680m for 400 bucks, maybe sell the 670ms for that amount or close to it(usd). Also if any of you have one to sell for a fair price ill buy it, or if you are interested in a 670m ill sell. Now when I bought this laptop at prostar they had the option of getting a 7970m for free, it was either 670m sli or 7970m, should I have gotten the 7970m and should I sell my laptop near the price i bought it for and just buy it over again, would I save money that way instead of replacing my graphics cards. 800 dollars is not a good price, I found that on eBay and that is ridiculous. Is there a way to buy this card directly from nvidia. Computer noob here so please don't hate.
