I read ppl have been experiencing some issues with the 7870, where it would not boot sometimes and in Starcraft and WoW it just wouldn't run or run glitchy. Is there really any texture glitch with this card?
i paid R$1280,00 for 570 (around US$ 700,00, i know, brazil sucks when it comes to technology) so i will be getting the 7870 with no extra costs. GTX 680 is over my budget, as it costs around US$ 1000,00.
I own a Sapphire HD7870 OC GHz edition for 3 weeks now. I have not played StarCraft or Wow on it, but I have played/playing at least 6 games, not to mention some 3D graphics as well and never had any issues.
I am still using the Catalyst 12.3 which was the first official driver to support these cards. Perhaps people with issues were using older drivers? (mind you the card was released before the official driver support, so the fact that it was working was not a guarantee that it will work properly).
In short, yes the HD7870 is more than a good replacement for the GTX570.
