**FX-6300 AND R9 270X CROSSFIRE PERFORMANCE HELP**

[WellBeyond3]

Hey everyone,

Recently, I purchased a sapphire r9 270x dual-x OC edition to crossfire with my sapphire r9 270x toxic edition. Everything installed fine, both graphics cards are working flawlessly, except during crossfire. I am constantly noticing that my fps is considerably lower (25-50 fps) during every game. I was looking into finding a fix for this problem, but I have not been able to come across anything (maybe its bottlenecking?). I was thinking about upgrading my CPU to an AMD fx-8350. But I'm not sure if that will help get my performance back, and increase it with the crossfire. I was also thinking that it may be my motherboard (Gigabyte GA-970-D3P) because for the PCIe-16 express slots, the first graphics card (toxic edition) is running at x16 and the second card (dual-x) is running at x4 during crossfire. I have a 650w 80+ power supply, so I don't believe that that is the problem. Any tips and advice would be lovely, I want to stick with an AM3+ motherboard, so any advice on what board I should get or what I can do to help get the most out of my crossfire would be greatly appreciated. Thanks everyone!

To be blunt.

 

A new CPU.

 

270x crosfire is as fast a single 290x about.

 

Considering perfect SLI scaling.

 

That cpu isnt enough to get good enough use from both cards im afraid.

 

Cheers.

To be honest, FX cpus aren't good enough for high performance gaming. They are ok for budget builds where getting a better gpu will help more than a good cpu, but if you want crossfire, you need a core i5.

Yeah to use the full potencial of his CFX even a 8320 would not be enough.

so save up a little more, switch motherboards and get a new processor? what ones would you guys suggest be best?

Thanks

Both of your cards are running at pcie 2.0 x4 speed which is a huge limiting factor for your cards...that's why you don't see FPS gains...also even on a good board at x8/x8 you CPU won' be able to feed these cards consistently 95%+ GPU loads but you should still get decent performance.

if you want to max out the cards and run them well you'd have to switch to an intel i5 and a new motherboard that supports crossfire (pcie 3.0@ X4 speed is fine for the R9 270X since it's the same as pcie 2.0 x8)

i will look into finding a motherboard that would be good! thanks for the advice!

you'd have no choice but to look at a 990FX motherboard and those cost a lot...it would probably be better to sell your AMD kit (CPU+MOBO) online to the most offering and get something up to date on haswell i5.

Something like this would be perfect and you could ask 100$ for your FX kit:

PCPartPicker part list / Price breakdown by merchant

CPU: Intel Core i5-4460 3.2GHz Quad-Core Processor ($179.49 @ OutletPC)

Motherboard: ASRock H97M PRO4 Micro ATX LGA1150 Motherboard ($79.89 @ OutletPC)

Total: $259.38

Prices include shipping, taxes, and discounts when available

where would a good site be to sell it?

i don't know it depends where you live you could always try to sell them on ebay or you could place an ad on a site similar to craigslist or kijiji (classified ads)

if you could afford a kit like that, yes you'd be golden...this CPU and board will be relevant to gaming for A WHILE...you will upgrade your GPU's again before you'd have to upgrade from this CPU...this is a beast.
