video card question!!

[adultswim810]

i know this is gonna sound really stupid but this is my first time shopping for a vid card
http://www.newegg.com/Product/Product.aspx?Item=N82E16814141070
how big of a difference?

these specs confuse me i thought that the 8800gts 640mb would kick the 8600gts's ass but according to this the only better parts are
Stream Processors 96
Memory Size 640MB
Memory Interface 320-bit

and the 8600gts actually has faster clock speeds
Core clock 675MHz
Memory Clock 2000MHz

so basically what im asking is how much do these things affect the performance of the card and which would be the better buy. please help.

Huge difference.

the 8800gts is almost 2x faster.

I'd get the 8800gts you could probably overclock to make it have the speeds of the 8600.

thanks guys im kinda stupid but i got one more question.
how do Stream Processors affect the performance? like what job do they do.

 

[Arcygenical]

Stream processors do everything. The more there are, the more simultaneous renderings/shading operations can be done every processor cycle. The 8800 is a *way* better buy.

come on guys !Waffles! is probably meaning he could overclock the core speed to be as fast as the 8600gts. of course the 8800gts is way better than the 8600gts and Nvidias midrange always have faster clocks because of the smaller process.
