Processing Cores:

I am still at to minds as to which card to buy now the 5770 has 800 Processing Cores and the rest is
Core Clock: 850MHz
- Memory: 1024MB GDDR5
- Memory Clock: 4800MHz (Effective)
- Memory Bandwidth: 76.8GB/s
the GTX260
Core Clock: 576MHz
- Memory: 896MB GDDR3
- Memory Clock: 1998MHz (Effective)
- Memory Interface: 448-Bit
- Processing Cores: 216
- Shader Clock: 1242MHz

What is the real difference in technology that makes them = in performance when there is such a clear difference in core & Memory speed and Processing Cores. How does the shader clock & memory interface on the GTX work when the 5770 dont have this tech.

Depends, if you want to play DX10 games get the GTX. If however you want DX11 features get the 5770.

how big a diffrence is there in DX10 & DX11 games, the game I play most is call of duty modern warfare 2 multiplayer and need for speed games I dont play anything else,
in fact is all the call of duty games I play. so is DX10 what I would use the most.

 

[Mr Paul]

I'd say the 5770 then
