This is not a question, but just a word of information:
The AMD 6000 and later series of cards are NOT compatible with the 1.1 series motherboards.
I was thinking of getting a HD 7770 myself but thankfully came across this article:
The final answer to the controversial PCIe x16 version compatibility.
So to all people having old motherboards:
DO NOT go for AMD cards. They WILL NOT work with your motherboard if it is PCIe1.1.

UPDATE: (After reading the comments I went back to researching again over this question and I must partly decline my statement of the PCIe configuration not being backward compatible. They in fact are very much compatible after a motherboard update (In some cases even the update wasn't needed. Sorry for the misguided information but I tried my best of reaching to the root of this controversy and reached a partially mistaken conclusion. So once again guys, if your graphic card doesn't work on your old motherboard then an UPDATE from from motherboard manufacturer will most likely solve your problem. My sincere apologies for any inconvenience or confusion caused. Thank you for all sharing your helpful experiences, as my final aim was to help ease the confusion and frustration that is involved with building a PC for the 1st time. Cheers to PC gaming!)

the guy who wrote the article was on tilt probably because a graphics card upgrade didn't work. or he had learnt the way it's meant to be played ;)

Actually it depends on the chipset.
Newer intel chipsets like the G31 and G41 have no problem (I can personally attest to it)
Some old chipsets like P5 did have some compatibility problems.

That's what I have.

ehh that's an old chipset. I would say it could be hit or miss in your case.

crap. the DO work on some 1.1 boards, i had that experience myself. I had a nforce 650i board and it was reported that many people had problems. the latest BIOS made it work. It also had an issue with the sli bridge, removed the pridge and re-seated a couple of times for it to work, but it worked. Its not pcie 1.1 its just certain motherboar bios's/configurations that just happen to be pcie 1.1
