Some advice please

[Dirt113]

I'm currently running a single AMD Radeon R9 270X (2GB GDDR5), and I want to CrossFire it with an additional R7 260X (2GB GDDR5)

 

1. Will I need an addition fan (or multiple fans) to withstand the heat output of both cards?

2. Is my DDR3 4GB RAM bottlenecking my graphics setup if I CrossFire it?

1) that depends if your cards run too hot when you put them together...you will need to find out for yourself

 

2) only if all 4GB are being used...check task manager during gaming

I'm not sure you can crossfire them because I don't think they're the same class chip.
