512MB would be more than enough if you don't plan to use SLI. With that resolution and a single 4670 card, by the time the VRAM is full by using AA and full quality settings, the GPU won't be able to cope anyway.

If you want to use SLI, the 1GB version will be preferable because the dual-GPU will cope with higher settings and might reach VRAM limits.

Also note that GTA IV loves VRAM, if you want to max view distance, you will need 1GB :p.
 
Unless the 1Gb card costs less, get the 512Mb version.
The extra 512Mb RAM will give you no performance gains unless you are gaming at 1920x1200 or higher (which you are not else you need to be getting a more powerful card).

What about playing FarCry2 at 1920x1080 on 512MB HD4850 with Ultra High settings? 1GB needed?
 
Yes but with 0xAA(You won't need it either because a resolution like that hardly has any jagged edges).
1GB may improve the performance in some areas but i don't think its needed since the 512MB version can handle it fine :)
 
Physics and PhysX are two completly differant things altogether.
Bottom line is if the OP wants to run a card on his currant PSU which is 400 Watts, then with out knowing more about the system the only sensable option is a 4670.
The OP's PSU may have a 6 pin adaptor for PCIE cards in which case i would say go get a 4770.
But based on the info we have the 4670 512 is the better option and 1 GB really isnt needed unless Maximum detail/quality is esential.

lets try this properly,
@ darkskoliro, Please can you post system specs and include the PSU make and model if you can.
We know you want to game at 1680x1050 so no need to include monitor info.
Once we know what your PC is like we can give you a better tailored sugestion as to what GPU would suit you better.

The 512 MB cards have 1000 MHz GDDR3 and the 1 GB cards have 900 MHz DDR3, so the 512 MB is faster as long as you don't need the extra RAM.
 


With that PSU, I would not run anything over a 4670 or 9600GT.
Even then, you are probably pushing it.
That PSU is dangerous and needs to be upgraded to a higher quality unit.
When you can afford it, get a new 450w+ PCP&C, Corsair, Seasinic or Antec Earthwatts PSU.
Take second and look at how ultra budget PSU's perform Here, Here, Here and Here (if nothing else, the first link is quite humorous).

Looking through the list of available GPUs and assuming you are on a budget, I would recommend the following cards to you.
Without upgrading the PSU, either get the 4670 512Mb card or this somewhat faster 9600GT 512Mb for about $14 more.
If you upgrade the PSU first, you can get this much faster 9800GT 512Mb for about $150.
 
I totally agree with outlw6669, your PSU really needs updating, in my view regardless of what card you want to run.
If its a budget thing then just get a 512 4670. If you can stretch to a new PSU and a card get a 4770 or 4850 from ATI or as suggested something along the 9800 lines from Nvidia
