OK - finally came to terms with my seller= $750 without the 4890 video card. NOW , which 5770 should I buy? I have heard a few of the 5770 sapphire cards were not functioning correctly. Is the high grade xxx or juniper cards worth the extra $10 or not? XFX, or Gibabyte or sapphire?? Will buy today so quick responses appreciated . The deal is that he comes to my house, installs my xp within the win7 - so I can use my 32 bit software in win7 64 - as I understand it, that is what needs to be done to play older games like Battlefield, Halo,etc. . and he changes out the cards , etc. SO, Not a great deal on the parts- but basically free labor/ knowledge/etc. - I will learn a few things as well. So, maybe have some confidence in building my own rig next time. Thanks again in advance... Ibaker- that thread on unlocking the 550 is very interesting, but I only got about 1/2 way thru it.
