I know some one has already asked a similar question before, but I am looking for specifics. I have a NF750-G55 mobo from MSI, which has a 750a nvidia chip set. I am using a Geforce gtx 260. I was thinking of buying a ATI HD 5870 (just one card, not SLI or Crossfire). my question is, how well will it work, what issues are there and is it worth it. Thanks.
