GPU for an Athlon II x2 250 (3.00 GHz) on a PCI Express x16 1.0 mobo

What would you recommend?

I was thinking HD5670 - HD6750, within that price range. Between these, which would you choose (and why)?

Sapphire Radeon HD5670 512MB DDR5 128-bit VGA
Sapphire Radeon HD6670 HyperMemory 512MB DDR5 128-bit
HIS Radeon HD6670 Fan 1GB DDR5 128-bit
Sapphire Radeon HD5750 512MB DDR5 128-bit
HIS Radeon HD6750 Fan 1GB DDR5 128-bit

Maximum monitor resolution is 1920x1080, although I can probably game at 1280x720 just fine, so I think 512 MB will be good enough.

Currently rocking 2 GB RAM (which I'll probably get another 2 GB module soon).

PSU is a 550 W noname.

Motherboard has PCI Express x16 1.0, not 2.0, so please take this into consideration. Do you know if this limitation even affects low-end to mainstream GPUs at all?
