Help me choose a GPU

Radeon 6750 or radeon 6770.

My PC specs,

2GB ram, core 2 duo processor(2.53GHz), intel DG31PR motherboard. I only have a 450 watts power supply..

I am a gamer(not so hardcore) play a lot of GTA 4 and other 3rd person games.

will it be useful if i get radeon 6750 and 2gb ram or radeon 6770 alone?

will 6770 run with my power supply?

What is your PSU's brand? The 6770 should work fine (it's only a $10 difference anyway). I'd recommend upgrading your system very soon though.

Cheap upgrade build, you can re-use the Case, HDD, PSU, DVD, and Vid (if you get the one above)

its 450 watts and it is Zebronics... and i have DDR2 slots for RAM

and i can add only 2GB ram per slot in my motherboard as it is restricted
