4870x2 + 4870

post #1 of 21
Thread Starter 
My friend is trying to sell me his Sapphire 4870x2. He only wants 50$ for it.
Should I pick this up and crossfire it with my current card? What kind of performance increase would I get? Crossfire set up easy?

$50 is absolutely nothing.... So i'm just debating on whether or not I want it based on time spent setting it up, and will it make a difference.

see below for rig details -

Thanks

Just as long as your PSU can power both, it'll work fine. Keep your current 4870 in the x4 slot and the 4870 x2 in the x16 slot.

Even if you DON'T use your current 4870, the x2 is a huge improvement.

Heck I'm sure you could sell your 4870 for close to 50 bucks. Free upgrade to an x2!

Man dont even think about it, just buy it. That is a steal for $50 if it works. You will see awesome performance at higher settings and resolutions
