video card what to choose

DUNNO.

In my hands, there were 2 boxes, HD3650 512-DDR2 and HD3650 256-GDDR3.
In all games, the higher the resolution, the more noticeable was the difference in favor of the HD3650 DDR3, and it was the exact same gpu.
The GDDR3 one was 10 bucks more expensive at that time (104 vs 115).
And I live in Uruguay.

Memory amount makes little to no impact if the gpu core can't handle it.
For 512mb, 8800gt or HD3870.
For 1gb, GTX 280 or HD4890.
