but only shows up as 8-8-8-20 latency when advertised 7-8-7-20 $155

worth exchaning for any of these options?
http://www.newegg.com/Product/Product.aspx?Item=N82E16820227381 - ocz platinum 7-7-7-24 - $145
OR
http://www.newegg.com/Product/Product.aspx?Item=N82E16820226050 - mushkin 6-7-6-18 $195
OR
http://www.newegg.com/Product/Product.aspx?Item=N82E16820145242 - Corsair XMS3 7-7-7-20 $155


I use this machine for mainly gaming/forums/music/pics and burning. Some photoshoop here and there as well. Was seriously considering the muskin 6-7-6-18 $195.

running i7 920
sapphire ati 5870

Thanks for input.

^ Actually you would have to set those rated timings in the BIOS...Read the comments and reviews of the users who have bought that memory...

And IMO there wont be any significant real-world performance difference between a CAS 6 and CAS 7 RAM...
