Is my motherboard fully compatible with my graphics cards?

[wolftown204]

I have an EVGA 141-BL-E757-TR LGA 1366 Intel X58 ATX X58 SLI LE Intel Motherboard

with 2 XFX HD-485X-ZDFC Radeon HD 4850 1GB 256-bit GDDR3 PCI Express 2.0 x16 HDCP Ready CrossFireX Support Video Cards.

Do these have any compatibility problems? They function together, but i have lower performance than expected, and some one told me that the graphics cards may be pumping out more information than the motherboard can process.

Well what I thing here is that the graphic card that you are using is not compatible with the motherboard that you are using. Actually the thing here is that if the graphic card have high standards I mean to say that it is higher than the system can sustain then you will definitely get the issues on the same. And here I guess you need to replace the graphic card that you are usi9ng and purchase the one which is compatible for the you system.
