Replacing HD7870 with RX580 8GB

post #1 of 9
Thread Starter 
Hello all,

I have a Sapphire HD7870 and I want to upgrade to ASUS RX 580. A friend of mine wants to buy the HD7870.
Currently in my country ( Bulgaria ) there are only RX570/580s available. and Nvidia 1050/1060/1070/1080. Nvidias are quite quite expensiveso pass.

My motherboard: http://www.asrock.com/mb/AMD/970%20Extreme4/
His morherboard: https://www.asus.com/us/Motherboards/P5KEWIFIAP/

If my friend takes the HD7870 and I buy a RX580 will be there a bottleneck for:
1) My friend when using the HD7870 ( http://www.sapphiretech.com/productdetial.asp?Pid=168D629A-8848-4CE2-8178-03C7EDE2AB7F&lang=eng )
2) Me using the RX570/580 ( https://www.asus.com/us/Graphics-Cards/ROG-STRIX-RX580-O8G-GAMING/ )

How much slower may the GPUs perform in that case ?

Thanks !

So, I’m guessing you have an FX 8 core like an 8350 and your friend either has a Core 2 Duo or Core 2 Quad.

Both will be fine as long as he also has an adequate power supply. You both would see decent benefits if you upgraded to modern platforms, but that doesn’t mean it won’t work as is. Your friend will certainly struggle to play modern AAA games. He could certainly be fine on most eSport games I would guess.

Not sure the prices where you’re at, but the cheapest modern platform would be a Ryzen 1200, the cheapest B350 board, and the cheapest ddr4 Memory.

Well, thanks.

We both have decent 1000 W PSUs, because in Bulgaria electricity service sucks and we have to be prepared, if we can't buy a decent UPS
( I have one but he does not ). My CPU is Phenom 2 X6 1090T @ 3.4 Ghz ( One thread per core FSB 2200 ). I am not bothered to build a new Rig now as mine is 4 years old and still holds biggrin.gif My concern is about my friend's video card is 512 MB and Borderlands 2 looking a lot awful. He has to play on low detail ( not resolution but rather effects explosions and stuff which drain a lot of VRAM ) to get decent fps
I am also not bothered how much RX580 will cost, because my friend cannot buy a decent card. rolleyes.gif However am not totally hooked on RX580 and I can have also 1060, 1070 or 1070Ti is still a decent option as long as the tems do not go high up. thumb.gif

The 1070 uses roughly the same amount of power as the 580, and is more efficient at idle. If you're going 580 for temperature concerns that's the wrong reason, go 580 for budget.

Given expensive 1060's, I would recommend you either go rx580 or 1070 TI.

Leaving this here just is someone asks about the parts: https://pcpartpicker.com/user/dvd_video123/builds/#view=wpjXsY

You can absolutely do what you like, my recommendation wouldn’t be to pair a 1070ti with a nearly 8 year old platform and processor. The more powerful the gpu you buy the more your platform is going to show its age. With a 1070ti, you would probably see as much as a 50 or 60 FPS deficite compared to someone using a 1070ti with a modern platform.

Completely do what you like. But your platform isn’t holding up like you may think it is.

Hmm, what GPU do you recommend though ... I see having 570/580 is pretty much what I can go for so far. Others are just not shipped to my country.

I do intend to getting Ryzen in 2-3 years though thumb.gif

I decided to go for the RX570 (Sapphire) because it costs a lot less and I will have to change RAM MB and CPU in the future. For now it is not worth it to by expensive card and change the base system later on, as the expensive card's price will go down to the floor when that day comes. Thanks all I guess I better stick with RX570 until the base system upgrade. If it holds for at least 2-3years it will be worth it ! And then AMD may release new chips better than Ryzen, though only the time will tell !

Cheers !
