Hi i am starting a computer build and was wondering if i get a hd 5870 will i be able to use it for eyefinity? i will be looking at getting another one in crossfire down the track is this a good idea? i want a 5970 but will have to wait months longer to be able to get one. i will wait if 5870 either single or crossfire wont be able to display eyefinity on maxish settings i play mw2..... the only reason i want 5870 is so i can get my computer up and running alot faster and then upgrade to crossfire to really exploit the 3 monitors
