GPU Compatabilty/Crossfire

[William12h]

I dont know of anyway to find out so im asking  

 

I have a AMD A10-7850k APU with R7 graphics 

 

I want to get a GPU.

 

So what im wondering is, Is it better for me to get a GDDR3 R250/R260 and run the GPU in Crossfire with the APU 

 

Or buy a better graphics card. 

 

 

R250 GDDR3 is around £70

And i dont want to spend lots on a GPU, under £200 but lower is better.

It would be better getting better.

GTX750ti is a great choice for budget builds

Get a 270, it will be more performance than CF, and it isn't that much more expensive than a 250

[PokémonTrainerFour]

Get a 270X or a 280.

[TeddyMcSwag]

If your PSU can handle it, get a 270, else get a 750ti.

My APU has around 720 stream processes and i OC to 1066Mhz, 

a 270x has 1280 stream processes.

 

If i was to get a R250 and crossfire i would get 384+ 720= 1104 stream processes.  and Getting a R250 is around £40-80 cheaper than a 270x.

 

I'm debating what one is worth it. 

 

I would get a 280/x but i dont see much diffrence between it and a 270x.

 

If i get a better GPU i may end up geting a Nvidia GPU. I would need to get a GTX 760 to get better stream processes.

ATM i only have a 350W PSU, but my CPU+HD use max of 110Watts.

 

My CPU uses between 20-100W. I will be getting a better PSU in time.

It's probably a really tight fit, but I think you can use the 270, and you can for sure use the 750ti, but that's a weaker card with less bang for the buck.

Exactly, Based on GPUBOSS  the GTX 760 and R9 270x are basicly the same (http://gpuboss.com/gpus/Radeon-R9-270X-vs-GeForce-GTX-760)

and my APU has better graphics than a 750 Ti...

Your APU does not even come near the performance of the 750ti. It might have more blah blah processors and a higher blah blah rate, but that does not matter. The 750ti beats the 7850k by far in game.

I used to have a 750, and the 7850k outperforms that, i only find it lacking in memory speed since it used DDR3 RAM and not GDDR5 RAM.

Looking at multiple game benchmarks, the 750ti performs as well as the 7850k does on medium, but on high (in fps). Also go watch Linus TechQuickie about GDDR5 vs DDR3.

Don't compare GPU's using stream processors

I know, i do take into account all the other specs and real life benchmarking. but i want speed

The 270 is around the same performance in most games, and there won't be any crossfire issues

Yeah, well ill be getting a 270x most probs or the GTX 660.

 

and i can't run it in Crossfire unless it uses GDDR3 RAM. 

 

Most prob 270x since everything in my pc is AMD or designed for AMD.
