I just want to us is there a huge difference between the 2 cards. HD 6850 is cheaper than HD 6870 I know that HD 6870 is the winner but is there a huge difference in performance? my monitor is 24" 1920 x 1080.
Is there a Nvidia card that same price as HD6850? what is that card? is that faster than HD 6850?
I game at 1080p and have a 6870 (although mine is oc'd to 1000 core/1200 memory).
If you are loking to max games at 1080p, I wouldn't go any lower than a 6870. From my experiences, I find I can max 90% of games with the 6870, and close to high settings on games such as Metro 2033, Battlefield 3 and Crysis 2.
I think if you are not going to oc your card, you should prob get the fastest card you can afford.
