I already have a Sapphire Radeon HD-5770 graphics card. It's OK but I'd like better performance. My question is would I be better off buying another 5770 and running them in crossfire or would a single 5870 give me the same result?
My Home Built System:
Corsair 800D Case
Asus P6X58D Premium MOBO
6 Gig Corsair Dominator 1866 RAM
Silverstone Strider 1000w PSU
Everything is under water except the GPU, since heat may become an issue I plan to add a second system for the gpu (gpu's) after I figure out what to do.
they are pretty close in performance. the crossfire option would obviously be the cheapest solution. if purchasing a new 5870 is not an issue then you would get better performance in games that don't yet support crossfire.
