4890 xoc and 4870x2

[hecjr82]

haveing a 4890 xoc crossfire and I add a 4870x2 with it , theres a chart in the forums that says it's comparable but I need to know if I'm reading the chart right

It is compatible, but I would advise against it.
Crossfire scaling after 3 cards is really bad, and the 4870X2 will bring your 4890s back to 4870 speeds, so the performance increase would be pretty close to nothing.

If you want, get another 4890, or depending on your Mobo, up grade to a pair of HD5850/460/470s.

thnks and what about haveing a 3rd 4890 xoc but it'll be in x8 not x 16 will it be running at half power or just alittle performance loss

X8 reduces the performance by about 3% for a 4890, so its not too big of a deal.
