Hi, I also have 4gb ddr2 Ram. I'm thinking about ddr5 version of gt730 or hd7750, but I worry about that the Athlon will bottleneck the card. What is the strongest GPU for my processor, which don't be bottlenecked? In next 3-4 months I will buy a whole new PC, For that reason my budget for the GPU is only around 50-60$ and I think to sell the gpu when I get the new computer. So what's your opinions ?
