7970 since it has 3gb opposed to 2gb which will help somewhat at 1440p, along with it having a wider memory bus. Though if i was you i'd wait till october for the new radeon cards.
Why? If he's looking at these two cards then the 9970 / 780 is going to be out of his price range.
aliasing problems are present at any resolution . the fact is most 1440p monitors (being 27 or 30 inch) are larger than 1080p monitors which are mostly 24 inch, . so the extra pixels are only making up for the larger screen size. if its at same screen size the extra pixels will improve image sharpness and maybe reduce aliasing errors but not eliminate aliasing problems. so Anti Aliasing is required even at high resolutions.

Well, I seen benchmarks on both and their very close at 1440p. However, the GTX card does have the extra PhysiX card and on top of that it has more memory units vs. the AMD (memory units are REALLY important when it comes to higher res.) It all comes down to what you want, but I prefer the Nvidia.
