I was wondering...I could get 2x 5770's for less than a 5850, and more stream processors...will there be more gaming performance with the two 5770's? What upgrade issues will I be facing in the future with the 5770? ASUS maximus formula MB, E6750 cpu
how about upgrade issues...5850 is 2.1 compliant. when 3.0 comes out is there going to be that big of a difference?

in short 2x5770 is a lot better value than 1 5850 but you will be restricted with upgrades unless you have a triple crossfire mobo, you could always trade in or sell when your ready for an upgrade don't worry about it being 2.1 its not going to make any difference to rendering its more the speed and will only effect ultra high end cards due to gddr and clock speeds
make sure the psu is strong its the heart of your computer
If you are going to overclock then definitely the HD5850. At stock the HD5770s win but the HD5850 surpasses them with an OC, especially minimum frame rates which is the most important performance stat. The HD5850 will also use less power, have no crossfire scaling/compatibility issues and leave the second slot free to use in the future. In general it is a never a good idea to start with a multi-card setup if there is a reasonable single card alternative.
