Radeon HD 4870 X2 and 4890 Crossfire?
I want to upgrade the graphics in my desktop (see system specs) and I've been seeing 4870 X2s on eBay from sellers with very good feedback for around $150-$200. Is it possible to Crossfire my 4890 with a 4870 X2? If not, I will probably still buy the card because dual-GPU and 2 GB of GDDR5 isn't exactly slow
Another issue is I'm not entirely sure if the cooling of my case is enough to do that safely or not... or even if my PSU could handle a triple-GPU setup.
