hmm 8600 is very ok for quake3 but he will not be ready for future games.
here you can see comparison between 8600 and 2900
http://www23.tomshardware.com/graphics_2007.html?modelx=33&model1=854&model2=857&chart=288
the 2900 is about as fast as a hd3870 which sells at 183 euro here in holland.
an 8600 is strong but will have trouble doing quake4 at a decent resolution and quality.

the hdr sm3.0 are about ingame effects i think and i dont have much knowledge of there numbers in benchmarks. higher is better offcourse. thats all i know.
if i must choose between 7950 or 2900 i choose 7950.
because of price and power consumption.
but if i must choose between 7950 or 3870.....

8800gt cost arround 400€ ...

and lol, good examples. sure is asynchron faster because the ram runs on higher frequence, omg: with otrher words: this has nothing to do with 1:1 or 4:5, it has to do with the ram frequency itself

for sure superpi is faster with a faster cpu and faster ram ;D

Athlons runs on asynchro were slower than same cpus runs on synchro. Second thing do u know what are u talking about? u cant run mem in other ratio than 1:1 4:5 2:3 1:2 ect. so what shitz are u talking?

compare cpu and ram speed, and check times, and u will see fucking ram speed influence on performance. ill give u tip cuz i see u have problem with almost everthing. SAME CPU ALMOST SAME CPU SPEED WHICH WONT CUT -30 sek but different is on ram speed 490 v 600.
