This is a discussion on 8800 GTX vs HD 5770 within the Video Card Support forums, part of the Tech Support Forum category. I i was wondering if I should upgrade to a 5770 i have gtx right now. Also cab te GTX
Well a PCI-E 3.0 card will work in a PCI-E 2.0 slot. Well no matter card you get will need a new 650W PSU. I recommend the one I linked. But here I found a HD 6850 for a good price Here is the like for the card. It is about $30 more than the 6770 but performs WAY better. here is the link
Any of the cards you mention represent a significant performance boost over your 8800. Will they play Starcraft II or Skyrim on ultra? Possibly, but at a low frame rate. For smooth game play you will need to be willing to spend several hundred more $$.
Alright I'm upgrading to a tx750 and a radeon hd 6850 with my amd phenom II 965 is this a good match and will it play starcraft II well doesnt have to be ultra :) tell me what you think. I'm getting tue xfx radeon hd 6850 jusy so you know this upgrade will run me 150$
