Would an Intel D975XBX motherboard be compatible with a Radeon HD 7770

While this board does have a PCI-E it is only PCI-E 1.0 and the Radeon HD 7770 is PCI-E 3.0 so while it may plug in and run it would most likely be bottlenecked due to the limited bandwidth of the slot and the processor in question. I would say that it is most likely time to upgrade your system if you are looking to move up to a PCI-E 3.0 video card. Heck an Intel Core i3-2100 and a H67 board would give you a big boost to performance.

Thanks for the tips  

However, I can't afford to spend more than 60-80$ on my new motherboard. I'd bought my HD 7770 but my old motherboard wouldn't boot with it. Since I already spent some money on my Video Card, I'm stuck to buy a motherboard that can atleast support it. I also cannot afford to buy a new processor.

Kinda looking to a little upgrade before buying the real beast.

Do you know any motherboard with a LG775 socket (for a Core 2 Duo processor) that atleast have a PCI-E 2.0 slot?

Edit 1: http://ca.asus.com/en/Motherboards/Intel_Socket_775/P5N... This motherboard appears to support PCI-E 2.0 and it only costs an extra 5$ when compared with the previous one. Could also get an Core 2 Duo E6550 (1333Mhz FSB instead of 1066) with that motherboard if it can be of any help.

Anyone? Are we talking about a really, really big loss of power there?
