Is it the “Z” in the model that makes my card unique, as mine had the fully enclosed cooler shroud, venting out the back of the PCIe slots. Other (available) models in the same line have the egg shaped cooler on them.
I’m sure the specs would be all the same, the only difference in the cooler ass’y. And being as anal as I am , I want to get the exact same card as I have.
However, I found a different manufacture (Diamond Multimedia & VisionTek) with the enclosed shroud. Once again, same specs, but I’m anal.
Now I’m looking into getting 2 5770 cards. Should I get the ones with the enclosed shroud? I found these:
Once again, the “Z” shows up in the model number. Is this the cooling ass’y desciption code or something?
I’m looking into the 5770 as they are 1” shorter then my 4870. The 4870 crowds my HHD cage: I can’t use the top slot, as I need room for the PCIe plugs. (I should suggest to the cards manufacters to put these plugs on the top on the cards, facing towards the "top" of the card, not towards the "back".) Also, the 5770 only needs 1 PCIe plug: it uses only 18W, vs. 90W for a 4870. Thus, I can keep my current PSU. And it supports DirectX11.
So, bottom line, is the enclosed shroud better at cooling, ‘cause it vents it out the case? Or are egg-shaped coolers just as good, as I see they have vents on the PCI Slot, too.
P.S. I think I found out that is the "A" in the model number.
P.P.S And my card is a "XXX" version of the XFX 4870!
You should be able to sell your XFX HD4870 for close to the expense of a HD5770. So the idea of getting 2x HD5770 is not far fetched. You will have the same performance as 2 x 4870 newer tech and less power consumption.
