no there will be near to none visable speed slowdowns if you are running on a x16 slot.
thanks i would pick this as best answer but i made the thread into a discussion not a question!
It didn`t work for me.
Kicking up a dead thread I know; but I don`t like to leave other peole reading persistently false information.
So I have a `HP` PCI-e 1.0 x16 Motherboard (Old Athlon x64 chip), and I have bought TWO HD7770`s over the months (PCI-e 3.0 x16) and NEITHER Work in the motherboard, no matter which drivers I try and use; after I read dozens of threads telling me thyat I could as all graphics cards are backwards compatible.
THEY ARE NOT.
You can only use up to a PCI-e 2.0 (NOT 2.1) x16 graphics card in a PCI-e x16 1.0 motherboard.
So; anyone want two HD7770`s barely touched.
The rig works perfect using an old X1950 XTX 512.
But I wanted 1Gb.
?
The best many people in a similar situation can hope for a up to a HD 4970 x2 or something.
After; the 5000 series you need a slot 1.1 or 2.0 or 2.1 Mo-bo
Kill the thread now?
