Why is it that nViida are still with GDDR3 but ATi are with GDDR5??
They perform the same, nVidia is not slower at all, not by much.

I think the diff is mem clocks, but i think nVidia must have better GPUs while ATi has better vram

mmm the GTX's were already in production when it was time to use GDDR5 in the mainstream. AMD just wanted to have something better then nVidia. the real question is why not use GDDR4 in the GTX's/4850 o_O

the difference between gddr3 and 5 is purely the memory clocks, which increase data throughput. the gpu architecture's used by nvidia and ati are completely different though so clock speeds wont translate over exactly.

This is because ATI and NVIDIA have different architecture. The type of VRAM does not determine if a card is better or not as well as the clock speeds. It's like trying to determine which goes better, a car or truck, even though are both doing 50 MPH.

There are lots of variation in VRAM. The speed in Ghz and speed in GB/S.
TBH just like in the PC in whole i look at the CPU, that being the GPU in a video card as that is the thing that renders all the 3D images. VRAM like someone said in a ealir post would be for the resolution or 2D images.
EDIT: Yet i could be wrong correct me if i am.
