How about a new 7950. This particular card has a great, has 3GB of VRAM to be able to pump up high graphic settings and play 1920x1080. Most people will say GTX 670. I'd get this 7950 because it's $309.99 after mail-in rebate
What do you think?
As far as used is concerned, you don't know if you have much warranty left on the card.
I looked at that card and it does seem to be able to play all current games at ultra, I was just worried about its performance a couple years down the line if I want to play games on high to ultra. What do you think about just getting one now, and in a year or so, (when they are cheaper) buying another to crossfire? How much of a performance boost would i see, and would it be big enough to justify a crossfire of 7950's over a crossfire of a 7870's?
And on a side note - would 400 or under be a good deal for a used amd 6990 or nvidia 590?
