I have been looking to upgrade my GPU lately. I would like to make an upgrade within the next three months, and have been keeping a close eye on prices. A friend pointed out to me that it may be worth considering an attempt at Crossfire configuration. After seeing some of the prices for a Radeon HD 6870, $50-80 bucks, I am actually considering it.
My question is: will my PSU be able to handle a second 6870?
Currently, my rig is running a FX-4170, but will soon upgrade to an FX-8350.
Any and all input is welcome.
My secondary question is: If a dual-6870 crossfire is possible with my rig, how would it compare to the alternative single GPU upgrade, with a *preferred* budget of around $200-250. ($300 absolute maximum.)
Oh wow; I had no clue that the newer generation of cards enjoyed that much of a performance advantage. (I guess it doesn't help I am looking at a higher price bracket at well. I think I got my 6870 for $160 dollars.)
Hm. I'll have to see if I can find more reviews that cover 6870 Crossfire configuration numbers, see if I can get a good approximation of the scaling I will get. $80 versus ~$200 is quite compelling, and even if my average increase/boost is around 50%, it still could very well be worth it.
After a lot of hemming and hawing, I have went back to the idea of just doing a single GPU upgrade. Your point of selling my old GPU and putting the costs towards the new seems to make the best overall sense. (Spending less now, with a cross-fire configuration, would most likely just create a headache for me later.)
For my desired performance gain, and bang-for-the-buck, the 760 seems to be in the sweet spot. I may hold out for a 280X, but we'll see how well I can managed my funds, as well as if any deals pop up.
