I have a rig with one RX 550 4 GB, one HD 7950 3 GB and one R9 290 4 GB. All mine ETC 59 MH/s @ 398 W at the wall (measured with power meter).

Also it's an 850 W PSU, only bronze rated.

RX 550: 11.35 MH/s
HD7950: 24.46 MH/s
R9 290: 23.13 MH/s

I'm trying to buy older AMD cards because they are really cheap and still profitable, if you known how to config them.

Weird that HD7950 is higher than R9 290, i think it should be close to 28-30Mh/s

R9 290 will give you a lot of hashrate, but it's very hard to find these cards in good condition.
Video cards HD7950, HD7970 (R9 280), R9 290 are very hot and they had a lot of overheating problems. When the 3XX series appeared, it helped a lot to solve overheating problems for miners.

Didnt know this cards were hashing that much, thanks for the tip! i sold my 7990r and finding replacements now
