Is crossfire worth it?

[Joseevb04]

So I have and RX 570 on my system, and there are other cards in my house (my father used to mine bc economy is kinda shit in my country so it was a good way of getting money, don't hate on me) and I was thinking about connecting another one and using crossfire to see if I can get more performance. So would it be worth it?

 

Another thing is that I think my motherboard has a 16x pci-e slot and a 1x, but we have some of those adapters that physicaly adapt a 1x slot to a 16x slot, so would it work with that?

 

And lastly, I have a pretty crappy system overall except of the gpu, so would it be worth it to just sell one of those gpus and get something different?

 

My specs are

 

Motherboard: Asus P7H55m-pro

CPU: i3 550 overclocked to 4.1ghz on the intel stock cooler

RAM: idk the branding, but I have 10gb DDR3 running at around 1335mhz bc of the oc

Storage: I have 2 hdds and a 120gb ssd

PSU: idk which one is it, but it's smthn like 700w

Crossfire is a negative value, to the point where you'll lose performance in games instead of gain anything.

No, no, and no. Your system probably can't even take advantage of 1 RX 570, let alone more. Plus, CF and SLI aren't really supported anymore. Not worth it at all. Also, your computer doesn't even support it in the first place now that I look at the motherboard model. 

[Joseevb04]

So... I shouldn't use it then... Fuck I was expecting to get some more performance without having to spend some money

Look into a CPU upgrade. Your GPU is fine, but you're using a low end CPU from 11 years ago that only has 2 cores. That's quite the bottleneck.

Alright, so what could I do? I've seen systems with i7 4770 and a compatible motherboard for around 300$, but those mb only have 2 memory slots so I would loose 2gb of ram, is it worth it?

Your motherboard doesn't even support crossfire.

Even that's so old it's become a bad value, you could get the cheapest ryzen or i3 today, cheapest compatible motherboard, and 16gb of ram for $300

Dropping down to 8GB of RAM would be a fine sacrifice to get a 4770 if that's a good price for your region.

Yeah but I live in venezuela, here the cheapest i3 costs like 300$ or more, and buying in amazon and shipping it would add like 100$ more and the posibility of people stealing my stuff

The i3-550 is DDR2, while the i7-4770 is DDR3, he's have to buy ram on top of buying the CPU and Motherboard.

Depending on Ram prices in the region, this might not be possible in his region.

Yeah, I've seen 6th gen i5 for around the same price but those are 4c/4t and I was looking for a 4c/8t one, I've had lots of problems with videocalls for classes and I don't wanna have to worry about it, I was also thinking about streaming a bit but I think that's impossible in my situation

No, the i3-550 is DDR3

No, not at all. The i3 was well into the era of DDR3. No Core i3/5/7 CPUs (mainstream models anyways) have ever used DDR2. OP wouldn't need new RAM.

My apologies, I should have done better research

Don't worry man! At least you didn't spend 3 hour trying to figure out why an old DDR2 stick that was lying around wouldn't fit in a DDR3 motherboard xDD (yeah I did that)

Fixed that for ya!

 

Back in the old days, SLi and CF support were enabled by drivers, it's different now, game devs are the ones that can enable SLi/CF support, and in a vast majority of the time, they don't bother with it as fewer and fewer peeps have SLi/CF rigs. Take it from someone who'd had CF and SLi rigs though out the years I've been into computers. My last CF rig was a pair of Vega64 (in my i7 3960X rig), while my last SLi rig was a pair of GTX Titan (in my i7 4770K rig). As of now, very few games support CF (pretty sure it's the same for SLi), and mostly older games, last game I recall seeing very good CF scaling was Strange Brigade.

 

These days, a single powerful GPU is more than enough for a vast majority of games. My RX 6900 XT framerate in Strange Brigade is just about there with my CF'ed Vega64's. OP, your system is too weak to take advantage of the benefits of running a CF system, with your CPU being a great bottleneck. Scrap the idea of getting a 2nd RX 570 and just bear with it, and save up for a totally new system build.

That totally sucks. I know what you mean though. In Argentina prices are much higher as well, but you can still build something decent by buying used parts. If you could make it here it would be awesome.
