Rx 550 4gb in crossfire or one Rd 480

[DrDerpCannon25]

Don't hate on me I'm amd person, my question is stated in the title. Should I put two rx 550 4gb in crossfire, or should I just use my current rx 480 4gb. Talk to me about clocks, as wells as whether lack of efficiency in crossfire is a problem or anything like that. Thanks guys! : )

Also I am moving this rx 480 to another pc if I end up deciding to take it out.

P.S. my other system specs are: fx 8350 cpu, Asus m5a97 r2.0 (not LE) a 1tb 7200rpm hdd and 12 4gb ddr3 ram. Also extra points if you can answer me this, if you go to the Asus m5a97 r2.0 page on the Asus website it says up to four way crossfire, and there is only 2 pciex16, how does that work.

Keep the 480. Crossfire and SLI does not scale 100% You will have overhead in drivers and some games just do not have dual card profiles and won't benefit at all. And two cards with 4GB do not make 8GB, as both 4GB has to have the same info loaded.

There were cards that had 2 gpu on them like the 7990 x2 and then they would crossfire to another card for quad.

Keep the RX 480, crossfire has issues and most games dont support sli's or crossfires that well. If you wish to upgrade, then RX 580 8 GB would be a better option. And moreover RX 550 is on par with 1050, so you are better off keeping the current GPU.

But If possible can you tell me what kind of inefficiencies there are in percent and if I'm betteextra points if you can answer me this, if you go to the Asus m5a97 r2.0 page on the Asus website it says up to four way crossfire, and there is only 2 pciex16, how does that work.r off getting a $200 dollar card. Also the bonus question: Extra points if you can answer me this, if you go to the Asus m5a97 r2.0 page on the Asus website it says up to four way crossfire, and there is only 2 pciex16, how does that work?

Your questions have been answered.

4 way crossfire with 2 slots, uses a special card that has crossfire on the GPU already. Then crossfire with a 2nd card to make 4 way. Here's a link to pics for a naked 6990.

radeon 550 vs 480 vs dual 550

cores 512 2304 1024
speed 1183 1266 1183

memory 4GB 4GB 4GB
speed 7GHz 8GHz 7GHz
bus 128-bit 256-bit 128-bit
width 112GB/s 256GB/s 112GB/s

Less than half the cores, less than half the memory throughput. Is it hard to make this leap? Less than half the performance. 550 crossfire will not replace your 480.
