OP just to prove how close R9 290 is to GTX 970, here is a benchmark of 2014 games done by gamegpu. At 1080p R9 290 is just 3% slower than GTX 970.

Used 290's are good value, it's a risk of course.
Many are probably not in good shape due to mining, this guy managed to break 200 of them.

Wat?, how do you break that many cards?...seriously, is mining really that hard on the cards?
It's not broken. It's refurb/used. Still under warranty and functional "As New".
Mining stress the fans moreso since ICs don't fail just because they are running as designed, within specs for the power circuitry. The reference blower is very resilient and very few "die" in my prior experience with mass retail. Generally I would be more concerned with open air blowers, under 100% fanspeed for 6+ months will wreck a few well known brand designs (won't name names).

Right, the only reason they are "close" is because that review is using reference models, and the reference clock speed for the GTX 970 is only 1050/1178 MHz, which is much slower than what the chip itself is capable of running at.
Sure, you mean just like how they are also using reference AMD R9 290's which run at 947MHz boost and are known to sometimes throttle the clocks even well below the 900 MHz range due to high thermals from the crap reference cooler? Both the 290 and 970 are capable of running well above reference speeds.
The point I'm making, is that you can potentially get a significantly greater amount of performance out of a GTX 970 than you can a R9 290 when both are overclocked.
The GTX 970 has a much lower TDP than the R9 290, whilst providing greater performance, and this is especially so when both are overclocked or running at high speeds.
That said, I do agree that the R9 290 is the bang for the buck champion at the moment. But if you care about energy consumption and overall performance, the GTX 970 is the better buy.

do you have the power usage for those overclocks? would love to see what is the actual difference.
Well since I am purchasing for him, I don't want to be held accountable if anything happens. Build quality is very important.
What happen if the GTX 970 fails?
Don't forget that the GTX 970 performance at 4k falls off like a rock compared to the R9 290.

Does it?

Must be one of them floating rocks. Seems it hangs with a 290X at 4K. And yes, you would want to SLI or CF these at 4K for the best performance. That goes for 290,290X,970,980, 780,780Ti.
Thanks for all the inputs guys. Finally I settled for the general idea of going used AMD. I chose a R9 280X DirectCU from a trusted seller. I have next day shipping for 185 CAD but I know the card is perfect. It will do all my friends needs for a more than decent price.
so no one has the power usage numbers and yet every nvidia fan is touting super power savings? 😕I'd be interested to see that too.
