Hello, guy....i have the Question about the GPU.

1. whis the GPU is the best With High Bit (320bit or 256bit) and what it means?
2. How this Bit thing can improve the performance GPU?

The bits are the size of data blocks that are processed. The longer blocks might make processing a little faster, depending on the size of the data being sent to it.

The difference between those two is relatively minor and will be swamped by many other GPU and video card characteristics. I suggest ignoring them and focus on performance reviews based on benchmarks of actual applications.

I was hoping for some significant performance increases when operating systems went from 32 bit to 64 bit - but the actual increase was very small. With operating systems, the big advantage of 64 bit seems to be that the 64 bit systems allowed adressing or use of more memory on the motherboard - and removing the old effective limit of about 3.2 to 3.4 GB.

ok now my PSU 1000wt, and im like to make the gtx 580 SLI or just buy the GTX 590. 1 more thing to add in AMD GPU witch card is the same place in GTX 580 and GTX 590
 
The 6970 is the top single GPU from AMD, but it's more of a match for the GTX 570 rather than the GTX 580. Even so the 6970 is a great card. As for the GTX 590 the Radeon 6990 would be it's AMD equal and while the 6990 seems to win more tests than the 590 (the difference between these cards is usually small) it seems the 6990 has a much louder fan. Even so, due to the fact that a 590 uses rather low clocks to stay in it's power limits two GTX 580s in SLI is generally significantly faster.
