So many uninformed posts from Nvidia fans in this thread it isn't even funny. ANYONE who compares a GTX770 to an R9 290 and believes it is even close is a fool... PERIOD. I cannot be nice about this, especially when it comes to them giving advice that will cost someone hundreds of dollars/euros/pounds listening to their idiotic advice. The constant talk of poor or unstable AMD drivers is clearly uninformed and based on nothing but conjecture ans wishful thinking. For every issue they can report I can do the same with Nvidia driver problems.
To the OP. An R9 290 should be compared to a GTX780, NOT a 770. Nvidia GTX780 is a brilliant card as is an R9 290. If you do go for an R9 290 stay away from the reference one with the truly horrible cooler. AMD really messed up with that cooler IMHO. Both Nvidia and AMD GPU drivers are stable and should cause no problems.
I am currently using an R9 290X in Elite and it is running at 2560x1440, max details at ~80 FPS, dropping to ~55 FPS in the Space stations. In contrast my spare GTX680 (which a GTX770 is a re-brand with faster VRAM) is getting ~25% less performance.
Here is a review of an R9 290 with GTX770 in there for comparison.

As far as prices go the GTX770 is $70 (Aus) cheaper than an R9 290 and a GTX780 is $110 (Aus) more expensive than R9 290 for similar performance. Clearly the GTX780 is way overpriced compared to the R9 290 so stay clear of it. Also bear in mind that the R9 290 comes with 4GB VRAM and with the extra ~20%-25% performance over GTX770, it will be far more future proofed.
The GTX770 is a decent card but its price/perf compared to R9 290 in Australian is poor.
