5770 (Juniper XT) vs 4870 vs 5770

[Sheeblasta]

I also looking at some graphics cards and I was wondering about 256mb vs 128mb but higher core speed? This would fit into a http://www.newegg.com/Product/Product.aspx?Item=N82E16813131398&cm_re=13-131-_-13-131-398-_-Product motherboard with a http://www.newegg.com/Product/Product.aspx?Item=N82E16819103471 or http://www.newegg.com/Product/Product.aspx?Item=N82E16819103656 cpu. Also I would like to know if there would be any better alternatives to the pieces I have already decided on.

Your video card links do not work. Also spec wise, the first two cards are HD 5770s, the only difference are the name brands and $5.

The HD 5770 is basically the equivalent of a HD 4870, but with DX11 and lower power consumption (61w vs. 125w)


The HD 4890 is more powerful than the HD 5770 for slightly more money.

The lower power consumption is due to the more advanced die size 40nm vs. the 4890, a CFX rig w/ one oc'd 4890 will be nearly as much as two 5770's at stock speed, that's quite a difference! However they are both similar in price, literally single digits. So it really depends on what sort of case cooling you have and your PCIe power supply.

This HD5770 for $155 with free shipping is a very nice deal;

That motherboards 2nd PCIe x16 slot is x4 so if you are considering crossfire in the future I would look elsewhere. At least x8 is what you want.
