well i'm confused..i've an intel dg41rq moterboard.......all motherboard specifications are saying that it has pci-e 2.0*16 slot ..but people on this site are saying that it has ..g41 express chipset which provides pci-e 1.1 slot ...so whats the reality.please i need someone to tell me the real version my mobo's pci-e *16 slot .i was going to buy a sapphire radeon hd 7750 but when I came to know that my motherboard has pci-e 1.1 .. ..and i know that amd graphic cards have problems with old pci-e versions .

You have nothing to worry about there, All PCIe x16 slots are backwards compatible. You can run x16 3.0 on an x16 1.0 just fine, with no performance loss.

but people are saying that amd hd 7000 series have some compatibility issues with older pci-e versions....

It should work fine with no problem. The only difference on PCIe 1.1 and 2.0 is bandwidth and its almost a non existent difference at that.

as the zotac website provides that their graphic cards will be compatible with pci-e 1.1 *16 slot (as if we take the case of gtx 650) and they are really compatible but when it comes to the amd hd 7000 series....they face problems with the older pci-e versions...(my friend has a 7770 which requires atleast a pci-e 2.0 *16 to function properly...older pci-e versions doesn't worked for his card) so what to do now...should I buy a nvidia gtx650 instead of a radeon hd 7750...will it consumes lot much power....will a generic 450 watts psu be enough for the gtx650...or can you assure me about the compatibility of an hd 7750 with my mobo

I would recommend going with the Nvidia in this case, mainly because the bandwidth and the 7750 requires power though the motherboard in a different ways. As for the power http://www.extreme.outervision.com/psucalculatorlite.jsp you can use that, its down for me so i cant check.

well i've found some people running hd 7750 on g41 chipset like me ....they told me that problem only arises with chipsets which are older than g31
